Product Specifications:
This solid carbide deep hole drill is built for one purpose: drilling deep, straight holes in tough materials. With a 6mm diameter and 185mm flute length (30×D), it can reach depths up to 168mm (28×D) without needing peck cycles. The 140° point angle and 30° helix are optimized for chip evacuation in deep bores, reducing the risk of flute packing – the most common cause of tool failure in deep hole drilling.
The ultra‑fine grain carbide substrate (HRA 92) provides exceptional rigidity and edge strength, while the AlTiN coating withstands high temperatures generated in deep‑hole operations. Recommended cutting speed: 40‑70 m/min, feed: 0.05‑0.10 mm/rev. Use high‑pressure external coolant (≥ 30 bar) aimed directly at the cutting edge. This drill excels on CNC lathes and machining centers with through‑coolant capability.
Applications include gun barrels, hydraulic cylinder rods, long shafts, and mold cooling channels – anywhere a deep, precisely sized hole is required. For depths beyond 28×D, consider our specialized gundrills. Custom diameters (4‑12mm) and longer lengths (up to 500mm) are available for OEM orders. Upgrade your deep hole machining with this reliable, high‑performance carbide drill.
