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.
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 Groove Pattern: This design helps contain metal shavings and expedites chip removal, promoting cooler and smoother drilling. The tip is split at a 118-degree angle for enhanced durability.
HSS Titanium Coating: Our high-speed steel drill bits come with a titanium coating that ensures outstanding durability and sharpness. The coating reduces friction and keeps the bits cool during use.
Easy Storage and Lifetime Guarantee: Our drill bit has a case for easy storage. 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.
