Drill bit Proline 76712 — single-piece metal/wood drill bit

Proline 76712 — single-piece metal/wood drill bit is a versatile replacement drill bit supplied as a single unit for use with handheld drills and drill presses. Constructed with a chromium-vanadium steel shank and a cutting tip made from special steels containing cobalt and tungsten, this drill bit is designed to deliver high hardness, improved abrasion resistance and enhanced temperature tolerance. It is intended for general drilling tasks in a variety of common materials including metal and wood and is compatible with standard chucks.

Advantages

The single-piece construction reduces the risk of separation between shank and tip while ensuring consistent concentricity during drilling. The chromium-vanadium steel shank provides strength and resilience, while the cobalt- and tungsten-enriched tip increases cutting hardness and wear resistance, extending service life in demanding conditions. Compatibility with standard chucks and suitability for both handheld drills and drill presses make this drill bit practical for straightforward replacement or single-size needs.

Suitable for

• Repair and maintenance work on metal and wood
• Home DIY projects requiring a single replacement bit
• Light to medium construction tasks using handheld drills or drill presses
• Drilling in a range of materials where a durable tip is needed

Key specifications

• Construction: single-piece drill bit (one unit)
• Shank material: chromium-vanadium steel
• Tip material: special steels with cobalt and tungsten
• Intended materials: metal, wood, glass, china, ceramics, concrete, marble, cast iron, plastic, glass fibre, granite, laminated materials, hardened steel
• Compatibility: standard drill chucks; suitable for handheld drills and drill presses

How to use

Install the Proline 76712 drill bit into a compatible drill chuck and tighten securely before operation. Select an appropriate drill speed and, if drilling into harder materials such as metal, glass or ceramics, use lower speeds and steady pressure to avoid overheating. For wood and softer materials, higher speeds and moderate pressure are suitable. When drilling through brittle materials like glass or ceramic, consider using lubrication or masking tape on the surface to reduce chipping. Allow the bit to cool between prolonged drilling intervals when working in demanding conditions.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves) and secure the workpiece before drilling. Match drilling speed and feed to the material being drilled, and replace the bit if signs of excessive wear or damage appear to maintain drilling accuracy and safety.
