## Summary description

Makita HSS-TiN metal drill bit, 8.5 x 102 mm with 1/4" hex shank. High-speed steel tip with titanium nitride (TiN) coating for increased wear resistance and longer life when drilling steel and other metals. Suitable for hand drills and impact drivers with 1/4" hex chucks; ideal for general metalworking, maintenance and fabrication tasks.

## Long description

Makita HSS-TiN 8.5 x 102 mm drill bit with a 1/4" hex shank is designed for drilling holes in steel and other metals. The cutting tip is made of high-speed steel (HSS) and finished with a titanium nitride (TiN) coating to enhance surface hardness and reduce wear. The 1/4" hex shank provides secure fitment in hand drills and impact drivers equipped with compatible chucks.
Advantages
The TiN coating improves abrasion resistance and extends tool life compared with uncoated HSS bits, while the HSS core preserves cutting performance and toughness. The 1/4" hex shank enables quick bit changes and stable torque transfer in both standard hand drills and impact drivers. The bit’s overall length offers enough reach for through-holes and common metalworking tasks.
Suitable for
 Drilling holes in mild steel, stainless steel and non-ferrous metals
 Maintenance and repair operations on metal parts
 Fabrication tasks, sheet metal work and mounting metal fasteners
 Use with hand drills and impact drivers that accept 1/4" hex shanks
Key specifications
 Cutting material: high-speed steel (HSS)
 Coating: titanium nitride (TiN)
 Diameter: 8.5 mm
 Total length: 102 mm
 Shank type: 1/4" hex for quick-change chucks
 Application: drilling metal
How to use
Select appropriate drilling speed and cutting fluid according to the metal type and thickness. Secure the workpiece and align the drill bit perpendicular to the surface. Insert the 1/4" hex shank into a compatible chuck until it seats firmly. Apply steady pressure and moderate speed; for stainless steel use lower speeds and intermittent feed to avoid overheating. Retract periodically to clear chips and, if possible, use cutting fluid to improve cooling and prolong tool life.
Usage recommendations
For best results when drilling harder metals, reduce rotational speed, apply cutting oil, and avoid excessive feed force. Replace the bit if wear or chipping appears on the cutting edges to maintain hole quality and dimensional accuracy.
