Drill bits Proline HSS-TiN 1.5 mm, set of 5

Set of five Proline HSS-TiN drill bits with 1.5 mm diameter. These drills are made of high-speed steel and finished with a titanium nitride (TiN) coating that increases wear resistance and reduces friction for cleaner holes. Each bit has a working length of 20 mm and a total length of 43 mm; the 135° point angle with adjustable chisel/slit geometry supports accurate centring and controlled entry when drilling metal and other materials.

Advantages

HSS substrate with TiN coating extends tool life and improves hole surface quality. The 135° point angle and ground flutes provide stable cutting and better control for small-diameter holes. Compact five-piece set gives a ready supply of identical 1.5 mm bits for repeated precision tasks.

Suitable for

• Drilling small-diameter holes in metal
• Precision work in electronics and model making
• General workshop and DIY tasks in wood and plastics

Key specifications

• Diameter: 1.5 mm
• Working length: 20 mm
• Total length: 43 mm
• Point angle: 135°
• Material/coating: HSS with TiN (titanium nitride)
• Quantity: set of 5

How to use

Secure the workpiece and clamp the 1.5 mm Proline HSS-TiN bit in the drill chuck. Use appropriate spindle speed and cutting fluid when drilling metals to reduce heat and extend bit life. Apply steady, moderate feed pressure; withdraw the bit occasionally to clear chips and prevent clogging. For plastics and wood, select lower speeds and lighter feed to avoid melting or splintering.

Usage recommendations

For best results when drilling metal, use cutting fluid, start with a centre punch for precise positioning, and keep speeds within recommended ranges for HSS bits. Store the bits dry and clean to preserve the TiN coating and prevent corrosion.
