Diamond flat bottom engraving bit in 16×45°x0.2x120L specification is designed for broad V-grooves, visible lettering, edge decoration and controlled shallow carving. The 16 mm shank fits a compatible precision collet, the 45-degree included angle forms wide profiles, and the 0.2 mm flat tip creates a defined groove bottom with more strength than an extremely sharp point.
16×45°x0.2x120L Diamond Flat Bottom Engraving Bit Overview
This geometry can support engraving on ceramic, tile, marble, stone and other abrasive materials when the cutter, machine and cooling method are correctly matched. Diamond cutting material offers wear resistance, while the flat-bottom profile helps control line width and depth. Actual performance depends on material hardness, spindle runout, machine rigidity, clamping and programmed cutting load.
Key Features and Buyer Benefits
- 16 mm shank for compatible CNC and engraving-machine collets.
- 45-degree profile creates wide V-grooves, lettering and decorative edges.
- 0.2 mm flat tip provides a controlled groove bottom and added point strength.
- Diamond cutting section supports wear resistance in suitable abrasive materials.
- Precision geometry supports repeatable details when runout and depth are controlled.
Typical Engraving Applications
A diamond flat bottom engraving bit can be used for stone lettering, tile decoration, shallow V-carving, identification marks, broad line work and edge details. The 45-degree angle is useful when the groove must remain visible without excessive depth. Always test an inconspicuous area or sample first because brittle surfaces, coatings and hidden defects can affect the result.
Machine Setup and Cutting Recommendations
Use a clean collet, keep tool overhang as short as practical and check spindle runout before machining. Secure the workpiece firmly and confirm that the programmed zero point prevents unintended deep engagement. Begin with a shallow step-down, conservative feed and suitable spindle speed. Inspect cutting sound, edge quality, dust or slurry condition and tool temperature before increasing productivity.
Cooling, water flow or dust extraction should be selected for the material and workplace rules. Never use a method that conflicts with the machine manufacturer’s safety requirements. Avoid dwelling in one location, forcing the cutter or making an aggressive first pass. Record the approved feed, speed and depth so the same diamond flat bottom engraving bit can produce consistent repeat work.
Inspection, Storage and Tool Life
Inspect the flat tip and cutting surface under good lighting before every job. Stop production if chipping, unusual vibration, excessive heat or deteriorating line quality appears. Clean residue with an appropriate method, dry the tool before storage and protect the cutting section from impact. Secure packaging is important because even small edge damage can change engraving width and finish.
Tool life varies with material abrasiveness, engagement, cooling, machine accuracy and operator settings. Buyers can review general information about diamond when comparing material properties. A documented inspection routine helps workshops and distributors evaluate tool life, cycle time and finished-surface quality across different jobs and repeat orders.

Product Description
This heavy-duty long-reach diamond flat bottom engraving bit features a 16 mm shank, 45° cutting angle, 0.2 mm flat tip and 120 mm overall length. The larger shank improves rigidity for demanding stone-carving equipment, while the extended body reaches recessed areas and large monument work.
It is designed for detailed engraving on marble, tombstones, ceramic and similar abrasive materials. The 45° profile produces controlled fine grooves, and the flat tip supports a defined base. Because of the 120 mm length, minimum practical overhang, accurate spindle runout and conservative feed settings are especially important.
Recommended Applications
- Ceramic, tile, marble and compatible stone engraving
- CNC lettering, logos and decorative groove carving
- Precision machining with controlled depth and stable workholding
