Drill bit Proline 91616, metal, Ø16 mm, length 160 mm, 1 pc

Single Proline 91616 metal drill bit with a 16 mm diameter and 160 mm overall length. Designed for drilling metal, the straight shank bit fits hand drills and drill presses and is intended for through-holes and larger-diameter metalworking tasks in construction, fabrication and repair applications. The bit is a single-piece solution offering centered drilling and compatibility with common drilling equipment used in professional and industrial settings.

Advantages

The Proline 91616 drill bit provides accurate centered drilling and reduced load during cutting thanks to its specially shaped cutting geometry. Its construction supports efficient chip evacuation with a double twist design for quick bore release. The straight shank design ensures secure clamping in standard drill chucks and machines, and the specified 160 mm length gives sufficient reach for many through-hole and deeper-drilling metal operations.

Suitable for

• Drilling through metal sheets and plates
• Fabrication and assembly tasks in workshops
• Repair and maintenance work requiring larger-diameter holes
• Use with hand drills and drill presses

Key specifications

• Material suitability: metal
• Diameter: 16 mm
• Overall length: 160 mm
• Shank type: straight shank for standard chucks
• Design features: double twist flute for efficient chip removal
• Package quantity: 1 piece

How to use

Secure the Proline 91616 drill bit in the chuck of a compatible hand drill or drill press, ensuring the straight shank is clamped firmly. Mark the drilling point on the workpiece and, if necessary, center-punch to prevent walking. Start drilling at a low speed to establish the hole, then increase speed appropriate to the metal being drilled while applying steady, moderate pressure. Use cutting lubricant when drilling tougher metals to extend bit life and improve cutting performance. Withdraw the bit periodically to clear chips and prevent clogging.

Usage recommendations

For best results, match drilling speed and feed to the specific metal type, use appropriate cutting fluid for heat reduction, and ensure secure clamping of both the workpiece and the bit. Inspect the bit for wear before use and replace when cutting performance or centering ability degrades.
