Drill bit Proline HSS-TiN 12.0 mm – straight shank, high-speed steel with titanium nitride coating

Proline HSS-TiN 12.0 mm drill bit made of high-speed steel with a titanium nitride (TiN) coating. The bit is intended primarily for drilling metal but is also suitable for wood and some plastics. It has a straight shank for use in standard chucks and provides improved wear resistance and more consistent hole finish thanks to the TiN layer. Diameter 12 mm, working length 101 mm, overall length 151 mm.

Advantages

The 135° split point with adjustable helix angle reduces walking and enables faster penetration into the material. TiN coating increases surface hardness and extends tool life while preserving cutting performance. Ground flutes ensure accurate concentricity and a clean hole finish. The straight shank fits common handheld and bench drills.

Suitable for

• Drilling through metal (steel, non-ferrous metals)
• General workshop and assembly tasks
• Woodworking and drilling certain plastics
• Handheld and stationary drill use

Key specifications

• Diameter: 12.0 mm
• Working length: 101 mm
• Overall length: 151 mm
• Material: HSS (high-speed steel)
• Coating: Titanium nitride (TiN)
• Point angle: 135° split point with adjustable helix
• Shank type: Straight shank

How to use

Secure the drill bit in the chuck of a handheld or bench drill, ensuring proper clamping on the straight shank. Select an appropriate speed for the material (lower speeds for harder metals) and apply steady pressure without excessive force. Use cutting fluid when drilling metals to reduce heat and extend bit life. Retract periodically to clear chips and maintain a clean hole.

Usage recommendations

For best results when drilling metal, use moderate drilling speeds and a suitable cutting lubricant. Store the bit in a dry place and avoid excessive side load to preserve the TiN coating and cutting geometry.
