- Unmatched Depth & Precision: Conquer deep-hole drilling challenges in steel, alloy, and stainless steel with our extra-long design. Choose from 2mm to 13mm in precise 0.1mm increments for the perfect fit, ensuring professional-grade results every time.
- Hardness & Wear Resistance – Crafted from Powder Metallurgy High-Speed Steel (PM HSS) with a hard AITiSiN coating, achieving 67 HRC. This extreme hardness allows the bits to cut through hardened steel, stainless steel, and alloys while lasting significantly longer than standard drills.
- Designed for Smooth, Efficient Drilling: The 118° self-centering point starts cleanly and reduces walking, while the optimized 4-flute spiral design ensures efficient chip evacuation. This means cooler operation, less binding, and faster, smoother holes.
- Professional-Grade Performance for All: Fully ground with H7 tolerance, these bits deliver exceptional accuracy for demanding CNC, milling, and drill press applications. Whether you're a machinist, fabricator, or serious DIYer, achieve workshop-quality precision at home.
- Complete Deep-Hole Solution Set: This practical 5-piece set provides incredible versatility for your most demanding projects. Custom sizes are also available, making this your go-to source for specialized drilling needs in metal, titanium, and aluminum.
