Drill bits Proline HSS-TiN 1.0 mm, set of 5

Set of five Proline HSS-TiN drill bits with 1.0 mm diameter designed for drilling metal. The bits are made of high-speed steel and feature a 135° point angle with adjustable chisel edge for precise centring. TiN (titanium nitride) coating increases wear resistance and improves hole finish. Working length 12 mm, overall length 34 mm.

Advantages

High-speed steel construction provides toughness for small-diameter drilling while the 135° point angle with adjustable chisel edge reduces walking and improves entry accuracy. The TiN coating extends tool life and enhances surface quality of holes. Compact set of five identical bits is suitable for repeatable precision tasks.

Suitable for

• Precise small-diameter drilling in metal
• Drilling in wood and plastics for fine work
• Hobby, model making and workshop repairs
• Light industrial and maintenance tasks requiring 1.0 mm holes

Key specifications

• Diameter: 1.0 mm
• Point angle: 135° with adjustable chisel edge
• Material: HSS (high-speed steel)
• Coating: TiN (titanium nitride)
• Working length: 12 mm
• Overall length: 34 mm
• Quantity: set of 5

How to use

Secure the workpiece and use an appropriate chuck that accepts 1.0 mm shanks. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material. Use cutting fluid when drilling metal to reduce heat and prolong bit life. Retract periodically to clear chips from the hole and maintain accuracy.

Usage recommendations

For best results drill perpendicular to the workpiece, use light feed pressure with small-diameter bits, and apply cutting fluid when working with metals. Inspect bits for wear and replace when the TiN coating is worn or corners become rounded to maintain hole quality.
