The 5D straight-shank internal-cooling solid carbide drill bit is a high-performance cutting tool specifically designed for medium-deep hole precision machining. Made from solid carbide material and equipped with an axial internal cooling channel, it enables efficient and stable chip evacuation and cooling at a drilling depth of 5 times the diameter (5×D). It is widely used for CNC machining of difficult-to-cut materials such as stainless steel, alloy steel, and cast iron.
- Efficient Chip Evacuation — Internal coolant pressure flushes chips from the bottom of the hole, preventing chip clogging and drill bit breakage.
- Extended Tool Life — Coolant reaches the cutting zone directly, reducing cutting temperature by 30-50%.
- Improved Machining Accuracy — The straight-shank design ensures high concentricity, with hole diameter tolerances achievable up to H7-H8.
