Mining and milling picks
Complete used picks and separated carbide tips. For suitable jobs we can separate the steel part and then clean the carbide components.
Technological services
Cemented carbide processing: separation, debrazing, cleaning and crushing
We specialise in technological processing of carbide inputs that are unsuitable for direct material use because of steel carriers, brazing alloy, size or composite construction. We design the solution according to the input type and required output.
Two forms of cooperation
We buy the material – or reprocess it as a service
Depending on the customer's commercial objective, we choose one of two modes. We either purchase the material in its current condition, or for suitable jobs carry out technological reprocessing and handle the output under pre-agreed terms.
A / DIRECT PURCHASE
You sell the material in its current condition
Suitable for customers who want a simple settlement without further handling of the waste.
- assessment of form and quantity
- price offer
- handover or collection
B / REPROCESSING
Processing as a standalone service
Suitable where the customer needs to separate the carbide fraction or reduce the material size.
- separation from steel carriers
- removal of brazing residues
- crushing oversized pieces
C / COMBINATION
Processing + subsequent purchase
For specific materials, the technological step can be combined with a subsequent commercial transaction by agreement.
- suitable for non-standard production waste
- individual calculation
- clearly defined input and output
Before processing
Identification, sorting and selection of the appropriate mode
For mixed and composite waste, the first step is correct material classification. Based on form, construction and available information, we separate material groups and decide whether direct purchase, reprocessing or a combined model makes more sense.
IDENTIFICATION
What the material contains
We work with part markings, material origin, tool construction and, where needed, material analysis.
SORTING
Separation into fractions
Carbide hard scrap, brazed parts, welded assemblies, soft scrap, tungsten alloys and HSS require different valuation and processing methods.
SOLUTION
Purchase or service
The customer knows in advance whether the material is being sold in its current condition or submitted for technological processing as a separate service.
01 / Separation
Separation of carbide from the steel carrier
Road-milling picks, mining components, brazed tools and other composite parts contain carbide in only part of their total weight. Processing aims to separate this valuable fraction from steel and other carrier materials.
✓milling picks and road bits
✓turning tools with brazed carbide tips
✓drilling and mining parts with carbide components
02 / Debrazing and cleaning
Brazed carbide is not worthless waste
In older turning tools, brazed tools and other parts, carbide may be bonded to steel with brazing alloy. For further material use, it is important to separate the carbide fraction and remove brazing residues as needed.
✓separation of the cutting edge or carbide segment
✓final surface cleaning from brazing residues and impurities
✓preparation for further trade or material recovery
CARBIDE SEPARATION
Milling heads and composite tools
In used milling heads and other composite tools, valuable carbide is often firmly bonded to the metal body.
We purchase these materials in their original condition and, depending on the construction, can also accept them for processing. The goal is to separate the carbide fraction from the carrier and prepare individual material fractions for further use.

Carbide cleaning
Debrazed saw tips: before and after oil removal
After carbide saw tips are separated from the steel body, oil, grease and fine process contamination may remain on the WC-Co material. We therefore degrease, clean and sort the material as required. The result is a cleaner and more controllable carbide fraction for further material use.
03 / Crushing and size reduction
We reduce oversized assemblies to a processable fraction
Large drilling heads, oversized carbide pieces or shaft assemblies may be unsuitable for further handling and recycling in their original dimensions. For selected materials, we carry out mechanical size reduction and crushing.
✓oversized carbide and tungsten alloys
✓mining and drilling heads
✓Morgan Rolls and other robust assemblies after individual assessment
Size reduction
WNi materials and tungsten heavy alloys
For suitable WNi materials, we also perform size reduction and crushing. The service can be combined with purchasing or provided as standalone reprocessing of customer material.
The customer receives a clearly defined acceptance method and agreed output form.
WNi materials
Technological flow
Every input is first classified by construction and material form
A different process makes sense for clean VBD inserts than for brazed tools, picks on steel bodies, Morgan Rolls on shafts or oversized drilling heads. Processing therefore starts not with a machine, but with correct input classification.
01
Acceptance
Material type, quantity, origin and form.
02
Sorting
Hard scrap, soft scrap, composite assemblies, W alloys.
03
Separation
Release of the valuable carbide fraction from carriers.
04
Cleaning
Removal of brazing residues and unwanted impurities according to input type.
05
Reduction
Size processing of robust and oversized assemblies.
06
Output
Separated and easier-to-handle material fraction.
Reworking / reprocessing
We can purchase the material or process it as a service
In industrial recycling chains, both direct purchase of secondary raw material and reprocessing of customer material are common. We select the appropriate commercial model according to the specific material.
01 / PURCHASING
Direct material purchase
We accept the material as our own input and determine the price according to type, quantity and condition.
02 / SERVICE
Reprocessing customer material
For suitable jobs, we perform the agreed processing step while the material remains part of the customer's material flow.
03 / COMBINATION
Individual arrangement
For more complex stocks, sorting, processing, purchasing and logistics can be combined by agreement.
Technical context · tungsten recycling
Why sorting, cleanliness and carbide separation from the carrier matter
Industrial tungsten recycling is not a single universal process. Technical literature distinguishes direct recycling, chemical (indirect) recycling, semi-direct routes and smelting metallurgy. The choice of subsequent processing depends primarily on waste form, cleanliness, composition and degree of contamination.
01 / HARD SCRAP
Solid sintered cemented carbide
SK/VBD inserts, solid-carbide drills and end mills, drawing dies, dies, wear parts and other solid WC-Co components. Well-sorted and clean material creates better conditions for efficient downstream recycling.
02 / SOFT SCRAP
Sludges, dusts, chips and powders
Fine production waste requires a different assessment. In industrial recycling chains, chemical conversion routes are often used for soft scrap and can also handle more complex inputs.
03 / COMPOSITE PARTS
Carbide + steel + brazing alloy
For milling picks, mining tools and brazed parts, pre-processing is a key step: dismantling, steel separation, removal of brazing alloy and concentration of the valuable carbide fraction.
Material flow
From waste to secondary raw material
Technical sources note that tungsten can be lost mainly through wear, dilution in another metal stream or disposal without separation. It therefore makes sense to capture tungsten-bearing material at the source, identify it correctly and separate it from steel or other carriers.
ADDITIONAL INDUSTRIAL INPUTS
Combined parts we can purchase and technologically process
In addition to standard inserts and solid-carbide tools, we also handle heavy and combined industrial parts. With these inputs, the valuable carbide or tungsten portion must be separated from steel carriers, contamination or other structural parts. The exact procedure depends on the material.
Dies and housings
Complete dies and other combined forming parts where carbide is joined to a metal housing. Material separation of the individual parts can be handled as a service.
Full rolls and large forms
We also accept large rolls and oversized forms. For combined assemblies we can handle separation of metal parts, material sorting and suitable dimensional preparation.
Mining and drilling crowns
Complete or worn mining and drilling crowns with carbide working parts. The material is assessed according to construction and the actual carbide content.
Carbide rings
Combined ring assemblies where the metal part can be separated from the carbide ring. Suitability for processing is assessed individually.
Large and long drills
Oversized and long drilling tools, including combined pieces with metal parts. Sorting and separation of individual material components can be arranged.
Do you have material that ordinary scrap buyers reject because of steel, brazing alloy or size?
These are exactly the materials that benefit from a technological assessment. Contact us and we will discuss the construction, quantity and required result.
