Drill bits set AWTools AW41165 — metal drill bit, 16.5 mm, white finish, 5 pcs

AWTools AW41165 metal drill bits are a set of five 16.5 mm diameter twist drills with a white surface finish, designed for drilling holes in a variety of ferrous and non-ferrous metals. The bits are intended for use with standard drill chucks and conventional drilling equipment in workshops and on job sites. This 5-piece set provides consistent hole size for fabrication, maintenance and repair tasks where a 16.5 mm metal drill is required.

Advantages

The set includes five identical 16.5 mm metal drill bits that deliver repeatable hole diameters and reliable drilling performance on sheet, plate and solid metal. The white finish helps protect the cutting surface from light corrosion and makes wear more visible during use. These twist drills are compatible with standard handheld and bench drills, offering straightforward installation in common chucks and stable cutting characteristics for controlled feed rates and accurate hole placement.

Suitable for

• Drilling holes in ferrous metals such as steel and cast iron
• Drilling holes in non-ferrous metals such as aluminium, copper and brass
• Workshop fabrication and metalworking projects
• On-site maintenance, repair and installation tasks
• Preparing holes for bolts, rivets or fasteners in metal components

Key specifications

• Drill type: twist drill for metal
• Diameter: 16.5 mm
• Finish: white surface coating
• Quantity: 5 pieces per set
• Compatible with standard drill chucks and drilling machines

How to use

Select a compatible drill chuck and securely tighten a 16.5 mm bit before starting the drill. Mark the drilling position on the workpiece and, if necessary, use a center punch to prevent wandering. Begin drilling at a moderate speed appropriate for the metal type, apply steady pressure, and retract periodically to clear chips and reduce heat build-up. Use cutting fluid when working with harder or thicker metals to extend bit life and improve hole quality. After use, clean chips from the flute and store the bits in a dry place.

Usage recommendations

For longer tool life and accurate holes, use appropriate cutting fluid, maintain correct spindle speed for the metal being drilled, and avoid excessive lateral force. Replace bits that show significant wear or chipping of the cutting edges to maintain hole accuracy and safe operation.
