| High Light | 55 Degree Helix Angle Spotting Drill ，Uncoated Solid Carbide Chamfer Cutter ，High-Precision Carbide End Mill | ||
This product is a High-Precision Uncoated (Bright Finish) Solid Carbide Spotting Drill / Chamfer Cutter. Unlike coated tooling, this spot drill maintains the razor-sharp edge of premium raw tungsten carbide. It is specifically engineered for machining operations that require maximum sharpness and minimal cutting resistance. It provides flawless center positioning to prevent subsequent drill walk, while doubling as an efficient tool for 90°/60° hole chamfering and V-groove milling.
Ultra-Sharp Uncoated Cutting Edge: The absence of a coating allows the cutting edge to remain incredibly sharp at a micron level. This razor-sharp geometry significantly reduces cutting forces and heat build-up, making it ideal for materials prone to work-hardening or gumming.
Premium Solid Carbide Substrate: Manufactured from high-density, micro-grain tungsten carbide, offering exceptional hardness and wear resistance. This ensures high tool rigidity under high-speed rotation, minimizing deflection and breakage.
Large Spiral Flute for Smooth Chip Removal: Features optimized dual spiral flutes with a highly polished finish. This design guarantees fast and unobstructed chip evacuation during high-speed machining, eliminating chip packing and protecting the workpiece surface finish.
Precision Straight Shank: The flawlessly ground cylindrical shank fits perfectly into high-precision hydraulic chucks, shrink-fit holders, or standard ER collets, ensuring minimal runout and superior concentricity.
Applicable Equipment: CNC machining centers, CNC milling machines, precision engraving machines, and high-speed drilling machines.
Best Target Materials: Aluminum, Copper, and Magnesium Alloys: Uncoated carbide is the premier choice for non-ferrous metals to completely prevent material welding and built-up edge (BUE).
Plastics, Acrylics, Wood, and Composites: Delivers clean, burr-free cuts without melting or tearing the material.
General Carbon Steel and light-duty metal alloy processing.
