Drill bit Proline 73537 — metal, Ø35 mm, length 370 mm, 1 pc

Proline 73537 is a single metal drill bit with a 35 mm diameter and a length of 370 mm, intended for drilling large holes in steel and other ferrous materials. Supplied as one piece, this Proline drill bit is designed to be used with compatible drill drivers or drill presses in workshop and industrial environments where a robust, straight-cutting metal bit is required.

Advantages

The drill bit provides a large-diameter cutting edge suitable for creating 35 mm holes in metal with a long reach of 370 mm that allows access to deeper workpieces. Its construction is intended to deliver consistent hole geometry and reliable chip evacuation for metalworking tasks. Supplied as a single unit, it is simple to mount and replace in standard chucks or holders compatible with its shank.

Suitable for

• Drilling holes in steel plates and structural metal components
• Workshop and industrial metal fabrication tasks
• Preparing holes for fasteners, bushings or pipe pass-throughs in ferrous materials
• Use with drill presses or heavy-duty handheld drill drivers

Key specifications

• Material target: metal and other ferrous materials
• Cutting diameter: 35 mm
• Overall length: 370 mm
• Quantity: 1 piece

How to use

Secure the drill bit in a compatible chuck or arbor and ensure the clamping system matches the bit shank. Mark and centre the drilling point, use appropriate clamping or fixturing to hold the workpiece, and select a suitable cutting speed and feed for the metal being drilled. Apply cutting fluid or coolant where recommended to reduce heat and friction, and clear chips as needed to maintain drilling performance. Use steady pressure and keep the drill aligned to the hole axis to prevent breakage or deflection.

Usage recommendations

For best results when drilling steel, use appropriate cutting lubricant, moderate spindle speeds, and secure workpiece clamping. Inspect the bit periodically for wear or damage and replace it if cutting performance degrades.
