Drill bit Proline 18 mm metal, model 76618, 1 pc

Proline drill bit 18 mm metal, model 76618, is a single high‑capacity cutting bit intended for drilling steel and a range of ferrous and non‑ferrous metals. Supplied as one piece, the bit is designed for use in standard drills and compatible metal drill holders in workshops, maintenance operations, and on construction sites where an 18 mm hole is required.

Advantages

The drill bit features a precisely ground tip and fluted body that support efficient chip evacuation and stable cutting through metal. Its geometry is tuned to reduce chatter and improve hole quality when working with common steels and softer non‑ferrous alloys. Being a single durable piece, it simplifies inventory and replacement for routine drilling tasks.

Suitable for

• Drilling through mild and medium‑hard steel
• Creating holes in aluminum, copper, and other non‑ferrous metals
• Workshop maintenance and equipment repair
• Construction and metal fabrication tasks requiring 18 mm holes

Key specifications

• Diameter: 18 mm
• Material compatibility: ferrous and non‑ferrous metals
• Supply format: single piece
• Suitable chuck types: standard drill chucks and compatible metal drill holders

How to use

Secure the drill bit in a suitable drill chuck or metal drill holder with correct clamping length and runout control. Select an appropriate spindle speed and use cutting fluid or lubricant when drilling tougher steels to extend tool life and improve chip evacuation. Start drilling at low speed to establish the pilot contact, then apply steady feed pressure and maintain coolant flow where required. Withdraw the bit periodically during deep holes to clear chips and prevent clogging.

Usage recommendations

For best results, match cutting speed and feed to the workpiece material: use lower speeds and cutting fluid for hard steels, and higher speeds for softer non‑ferrous metals. Inspect the bit before use for wear or damage and replace it if the cutting edge is blunt to ensure consistent hole quality and operator safety.
