8mm Shank 120° x22mm Brazed Diamond Conical Bit
An brazed diamond conical bit from JEEFOO in Guangzhou, China is designed for conical carving, grooving, shaping and localized stock removal on granite, marble and other abrasive mineral materials. Vacuum-brazed diamond grains are firmly exposed on the working surface, helping the tool start cutting quickly while maintaining useful chip space.
Main Applications and Material Range
- Granite and marble edge trimming
- Stone relief carving and surface shaping
- Localized cutting, repair and detail work
- Compatible engineered stone and mineral board after a test cut
This A13 profile uses an 8 mm shank, 120-degree cone and 22 mm head. Selection still depends on stone hardness, spindle power and the finish required. Granite normally needs conservative engagement and reliable cooling or dust control, while marble may permit a faster pass but still requires edge-support care.
How Brazed Diamond Cutting Works
Unlike a conventional carbide edge, diamond grains remove stone through controlled abrasion. A single brazed layer exposes sharp particles and open spaces that help evacuate stone powder. The tool should cut continuously without excessive dwell. Heat, vibration and trapped dust can shorten working life or leave an uneven surface.
CNC Setup and Operating Guidance
Before using a brazed diamond conical bit, verify the shank and collet match, keep runout low and secure the workpiece. Start with a shallow pass and moderate feed, then adjust according to spindle load, sound, dust generation and surface quality. Avoid forcing the tool into a full-width cut at maximum depth.
Use wet cooling when the machine and application permit it. For dry cutting, apply effective extraction and follow the machine maker’s limits. Operators should wear suitable eye, hearing and respiratory protection because stone dust can be hazardous.
Finish Quality and Tool Life
Stable fixturing, small radial engagement and consistent motion help a brazed diamond conical bit produce cleaner edges. Do not allow the tool to rub in one location. If cutting efficiency falls, stop and inspect for loading, damaged diamond coverage, excessive runout or unsuitable parameters.
Why Source from JEEFOO
JEEFOO supplies CNC cutting tools from Guangzhou, China and can help buyers confirm dimensions, profiles and intended stone applications. When requesting a quotation, provide the stone type, machine, spindle interface, working depth and required finish so the brazed diamond conical bit can be matched more accurately.
Frequently Asked Questions
Can it cut both granite and marble? Yes, when the profile and operating parameters suit the material. Always begin with a controlled test cut.
Should it be used wet or dry? Wet use may improve cooling and dust control, but compatibility depends on the machine. Use extraction and proper PPE for dry work.
What causes premature wear? Excessive depth, low feed that creates rubbing, poor runout, vibration, heat and inadequate dust removal are common causes.

Product Description
This A13 brazed diamond stone bit features a 8 mm shank, 120-degree profile and 22 mm conical head. The vacuum-brazed diamond surface provides aggressive material removal and dependable wear resistance on abrasive mineral materials.
Use this profile for CNC or handheld stone carving, shaping, grooving and relief work on granite, marble, ceramic and engineered stone. Match speed, feed and cooling to the profile and material.
Recommended Applications
- Granite and marble carving
- Stone shaping and grooving
- Ceramic and engineered-stone work
Before production, record the spindle speed, feed rate, pass depth, cooling method and observed finish. This process data makes the next brazed diamond conical bit setup faster and helps operators detect changes in tool condition before they affect stone quality or dimensional accuracy.
