Drill bit for metal Makita HSS-TiN 3.2 x 67 mm 1/4" HEX

Makita HSS-TiN 3.2 x 67 mm drill bit with a 1/4" hex shank is designed for drilling metal with handheld drills and impact drivers that accept hex shanks. Made from high-speed steel (HSS) and finished with a titanium nitride (TiN) coating, this bit combines the toughness of HSS with improved surface hardness and reduced friction from the TiN layer. The 3.2 mm core and 67 mm overall length provide access to thin sheets, profiles and through-holes while the 1/4" hex shank ensures secure engagement in quick-change chucks and bit holders.

Advantages

The TiN coating increases wear resistance and helps maintain cutting sharpness under continuous use. High-speed steel construction offers good toughness and heat resistance during drilling of ferrous and non-ferrous metals. The 1/4" hex shank gives reliable torque transfer and quick bit changes without additional adapters. The combination of material and coating supports consistent hole quality and longer tool life compared with uncoated HSS bits.

Suitable for

• Drilling holes in thin metal sheets and panels
• Making pilot holes in metal profiles and sections
• Light to medium-duty workshop and on-site metalworking
• Use with hand drills and impact drivers accepting 1/4" hex shanks

Key specifications

• Drill diameter: 3.2 mm
• Total length: 67 mm
• Material: high-speed steel (HSS)
• Coating: titanium nitride (TiN)
• Shank type: 1/4" hex
• Recommended use: metal drilling (ferrous and non-ferrous)

How to use

Mark the drilling location and secure the workpiece to prevent movement. Fit the 1/4" hex shank into the drill or bit holder and set an appropriate speed for metal drilling—moderate speeds for small diameter HSS bits reduce heat buildup. Apply steady, even pressure and allow the bit to cut without excessive force. Use cutting fluid or coolant when drilling thicker or harder metals to prolong bit life and improve chip evacuation. Withdraw the bit occasionally to clear chips if drilling deep holes.

Usage recommendations

For best results, use light cutting lubrication when drilling steel and increase coolant for stainless steel or harder alloys. Replace the bit if cutting performance or hole quality deteriorates, and store in a dry place to avoid corrosion.
