Dormer Drill Bit HSS 27/64″

Superior Heat Resistance The TiN-Tip coating allows for significantly higher cutting speeds and feeds compared to standard HSS bits. It acts as a thermal barrier, keeping the cutting edge sharp even during prolonged use.

No-Wander Split Point Equipped with a 118° split point geometry, this bit is self-centering. It bites into the material instantly, eliminating the need for a center punch and ensuring a perfectly centered hole.

Efficient Swarf Removal The specialized flute design is engineered to evacuate metal chips and swarf rapidly, preventing the bit from binding and reducing the risk of overheating in deep-hole applications.

Versatile Material Range Optimized for consistent performance across a wide variety of materials, including carbon steel, alloy steel, grey cast iron, and aluminum.

Steam Tempered Finish The blue-tempered finish on the body improves the bit’s ability to retain cutting lubricants, which further reduces wear and ensures a smooth internal hole finish.

Industrial Standard Precision Manufactured to ANSI standards, ensuring high-tolerance diameter accuracy for critical engineering and maintenance tasks.
