Drill bit Proline 76190P — metal bit 19 mm, length 198 mm, 1 pc

Single Proline 76190P drill bit for metalworking with a 19 mm diameter and a total length of 198 mm. Manufactured from HSS refined steel and compatible with DIN 338 standard, this solid metal bit is intended for drilling holes in steel and other metals. The relief length of 13 mm provides effective chip removal and heat dissipation during through-hole and deep-hole drilling. Supplied as one piece in a PVC case, the bit fits standard chucks and is suitable for workshop, maintenance, and professional repair tasks where a large-diameter metal drill is required.

Advantages

The HSS refined steel construction ensures good hardness and wear resistance for metal drilling. Compliance with DIN 338 guarantees consistent geometry and compatibility with common drilling equipment. A 13 mm relief helps reduce friction and improves chip evacuation, while the 198 mm overall length allows access to deeper workpieces. The PVC case protects the cutting edge during storage and transport.

Suitable for

• Drilling through steel and non-ferrous metals
• Workshop and maintenance operations
• Professional repair and fabrication tasks requiring a 19 mm hole
• Use with drill presses and handheld drills with appropriate chucks

How to use

Secure the drill bit in a compatible chuck, ensuring proper seating and tightening. For metal drilling, mark the centre point and use a suitable pilot or centre punch to prevent wandering. Start at low speed and apply steady pressure; increase speed as the bit engages the material while maintaining coolant or cutting fluid to extend tool life. Use appropriate clamping and protective equipment. After use, clean chips from the flutes and store the bit in its PVC case to protect the cutting edge.

Usage recommendations

Use cutting fluid or coolant when drilling steels to reduce heat and wear. Select drill speeds and feed rates appropriate to the workpiece material and machine capability. Inspect the cutting edges regularly and replace the bit when wear or chipping reduces drilling quality.
