Drill bit Proline 76150P — metal drill Ø15 mm, length 169 mm, 1 pc

Proline 76150P is a single high-speed steel (HSS) metal drill bit with a 15 mm cutting diameter and a total length of 169 mm. Manufactured to be compatible with the DIN 338 standard, this drill bit is intended for drilling through-holes and fitting tasks in various metalworking applications. The tool features a standard shank for secure clamping in bench and handheld drills and is supplied in a protective PVC case for safe storage and transport.

Advantages

The HSS refined steel composition provides good hardness and heat resistance for drilling into steel and other metals at moderate speeds. Compatibility with DIN 338 ensures consistent geometry and performance when used with standard drill chucks. A relief length of 13 mm supports chip clearance and reduces friction along the fluted section, while the included PVC case protects the cutting edges and simplifies handling.

Suitable for

• Drilling through holes in mild and alloy steels
• Automotive repair and maintenance tasks
• Metal fabrication and fitting operations
• Workshop and construction site drilling with bench or handheld drills

Key specifications

• Material: HSS refined steel

How to use

Secure the drill bit firmly in the chuck of a bench or handheld drill, ensuring proper alignment and clamping to prevent wobble. Select an appropriate drilling speed for HSS into metal—moderate RPM depending on workpiece thickness and material—and apply steady, even pressure. Use cutting fluid or lubricant when drilling steel to reduce heat buildup and prolong tool life. Withdraw the bit periodically to clear chips through the flutes and maintain cooling.

Usage recommendations

For best results, begin with a smaller pilot hole when drilling large diameters to reduce axial load and improve centring. Match drilling speed and feed to the metal type: lower speeds for harder alloys and higher speeds for softer materials. Store the drill bit in its PVC case to protect the cutting edges and avoid corrosion.
