Drill Bit Art-Pol 7.5 mm for Metal, white coating, model 53075

Art-Pol 7.5 mm drill bit for metal with white coating, model 53075, is a straight-shank twist drill designed for drilling metal surfaces. It is intended for creating 7.5 mm diameter holes in a variety of ferrous and non-ferrous metals and fits standard chucks on handheld drills and drill presses. The white surface coating provides improved visibility and basic protection against corrosion and wear during typical workshop use.

Advantages

This metal drill bit features a straight shank for secure clamping in common chucks and a geometry suitable for efficient chip evacuation when used at appropriate cutting speeds. The white coating reduces surface friction and helps maintain drill life in routine metalworking, repair and assembly tasks. The 7.5 mm diameter offers a precise hole size for fasteners and through-holes where that nominal size is required.

Suitable for

• Drilling through steel plates, aluminum sheets and other common metals
• Workshop repairs and maintenance tasks requiring 7.5 mm holes
• Assembly of structures where standard fasteners or clearance holes of 7.5 mm are specified
• Use with handheld electric drills and bench drill presses with standard chucks

Key specifications

• Diameter: 7.5 mm
• Material application: metal (ferrous and non-ferrous)
• Shank type: straight shank, suitable for standard chucks
• Surface finish: white coating for reduced friction and basic corrosion protection
• Tip type: standard twist drill geometry for general purpose metal drilling

How to use

Mark and center-punch the drilling point to prevent wandering. Secure the workpiece and select an appropriate cutting speed and feed for the type and thickness of metal being drilled. Use cutting fluid or lubricant for improved heat dissipation and chip evacuation when drilling harder metals. Clamp the drill bit securely in the chuck, align perpendicular to the surface where a straight hole is required, and apply steady pressure until the hole is completed. Retract occasionally to clear chips on deeper holes.

Usage recommendations

For best performance, pair the 7.5 mm Art-Pol metal drill bit with appropriate cutting fluid, correct drill speed for the metal type, and proper clamping of the workpiece. Inspect the bit periodically for wear and replace when the cutting edge becomes dull to maintain hole quality and to reduce the risk of overheating or breakage.
