About this item
- HSS Titanium Coating: Our high-speed steel drill bits feature a titanium layer that guarantees exceptional durability and sharpness. This coating minimizes friction and helps maintain a cool temperature while in operation.
- Widely Applicable: Our step drill bit can process different diameter holes, making it easy to drill through plastic, wood, plank, and soft rubber with low hardness countersunk. Suitable for home DIY and general building/engineering use.
- Spiral Flute Design: The spiral-flute design prevents metal filings from flying around and clears chips faster, allowing for smoother drilling without overheating. The split point tip is at 118 degrees to increase wear resistance.
- Easy Storage and Lifetime Guarantee: We stand behind all of our high-quality products and offer a no-questions-asked guarantee. If you're not satisfied, please contact us (through here if past the standard return window) and we'll be happy to assist you.
- Hex Shank for Quick Change: Our drill bits feature a hex shank that fits easily and securely into all power tools, especially for locking into quick-change chucks. The hex shank also clamps more securely onto pistol drills to prevent slippage and shedding during rotation.
