Dormer Drill Bit HSS 29/64″

Advanced TiN-Tip Coating The Titanium Nitride coating at the point increases surface hardness and lubricity. This results in less friction, lower heat buildup, and a significantly longer tool life during continuous operation.

Precision Split Point Equipped with a 118° split point, this bit is self-centering. It bites into the material immediately upon contact, preventing “drill bit wander” and ensuring accurate hole placement without the need for a center punch.

Optimal Chip Evacuation The specialized flute geometry is designed to pull swarf and metal chips out of the hole efficiently, which prevents overheating and allows for smoother drilling in deeper materials.

Wide Material Range Engineered for high performance across various materials, including alloyed and non-alloyed steels, cast iron, and non-ferrous metals such as aluminum.

Steam Tempered Body The “blue finish” steam treatment on the flutes helps retain cutting oil and coolant at the cutting zone, further reducing wear and ensuring a clean internal finish.

Industrial Consistency Manufactured to ANSI standards, ensuring that every bit meets strict tolerances for diameter accuracy and structural integrity.
