Drill bit Proline 76185P — metal, Ø 18.5 mm, length 198 mm, 1 pc

Proline 76185P drill bit for metal, single piece, with an 18.5 mm diameter and 198 mm overall length. Manufactured from HSS refined steel and produced to DIN 338 geometric standards, this straight-shank drill bit is intended for drilling holes in steel and other metal workpieces. The cutter features a 13 mm relief and is supplied in a PVC case for storage and transport, offering a robust option when a medium-to-large bore is required.

Advantages

The HSS refined steel construction provides higher hardness and wear resistance compared with standard carbon drills, enabling consistent cutting performance in metal. Conformance with DIN 338 geometry ensures predictable chip evacuation and stable drilling behavior. A 13 mm relief reduces friction at the cutting edge and helps maintain cutting efficiency during prolonged use. Supplied in a PVC case, the bit is protected from damage and corrosion during storage and transport.

Suitable for

• Drilling through mild and alloy steels
• Workshop and maintenance tasks requiring medium-large holes
• Construction and repair work on metal components
• Use with standard drill chucks and drill presses

How to use

Secure the drill bit in a compatible drill chuck ensuring correct alignment and sufficient clamping length on the straight shank. Select an appropriate rotational speed and feed rate for the workpiece material—lower speeds for harder metals and higher speeds for softer alloys—while applying steady pressure. Use cutting fluid or lubricant to reduce heat and improve chip evacuation when drilling through steel. After drilling, withdraw the bit while the spindle is still turning to clear chips, then stop the drill and inspect the hole and cutting edge for wear.

Usage recommendations

For longer tool life and consistent hole quality, start with a pilot hole when applicable, apply a suitable cutting fluid, and avoid excessive feed that can cause bit breakage. Store the bit in its PVC case to protect the cutting edges and prevent corrosion.
