- 【M42 8% Cobalt for Superior Hardness】Engineered with premium M42 High-Speed Steel containing $8%$ Cobalt, the RiNTREE drill bit offers exceptional red-hardness and wear resistance. It stays sharper longer than standard HSS or M35 bits, making it the ultimate tool for demanding industrial tasks.
- 【Optimized 135° Split Point】 The precision-ground 135-degree split point starts drilling instantly on contact. It prevents "walking" or skating on hard surfaces, ensuring a clean and accurate hole without the need for a center punch.
- 【Advanced TiN Coating】 Featuring a high-performance Titanium Nitride (TiN) coating, this bit significantly reduces friction and heat buildup. This protective layer extends tool life by up to 3 times, allowing for faster cutting speeds and smoother chip evacuation.
- 【Versatile Industrial Application】 Specifically designed to penetrate tough materials with ease. Perfect for drilling through Stainless Steel (SUS304/316), Cast Iron, Grade 8 Bolts, High-Temperature Alloys, and other hardened metals where ordinary bits fail.
- 【Standard Jobber Length & Straight Shank】 The universal straight shank fits most standard drill presses and handheld drills. The jobber length provides the ideal balance of rigidity and reach for a wide variety of automotive, aerospace, and DIY maintenance projects.
