Hole Making

DOHRE CNC offers a complete range of hole making tools, including carbide drill bits, boring cutters, and reamers. We also provide deep hole drill bits, aluminum drill bits, DLC coated drills, internal cooling drills, and external cooling drills for different machining requirements.

Carbide drill bits are used to create the initial hole, boring cutters are used to enlarge and refine an existing hole, and reamers are used to achieve final hole size accuracy and smoother surface finish. Choosing the right tool depends on whether your priority is hole creation, diameter correction, or precision finishing.

If your priority is final diameter accuracy and smooth internal surface finish, reamers are usually the better choice. If you need to adjust an existing hole or improve alignment before final finishing, boring cutters are more suitable than standard drill bits.

Our hole making tools are suitable for steel, stainless steel, aluminum, titanium, and other alloys. With micro-grain carbide substrates and coating options such as TiAlN, AlCrN, and DLC, they are designed to maintain stable cutting performance across a wide range of industrial machining materials.
