Drill bit set AWTools AW42316 — 13-piece titanium-coated metal drill bits 1.5–6.5 mm

AWTools AW42316 is a 13-piece drill bit set for metal that includes titanium-coated high-speed steel bits in sizes from 1.5 mm to 6.5 mm. Designed for drilling through metal and other hard materials, the set covers small to medium diameters commonly used in precision work and general workshop tasks. The bits are compatible with standard hand drills and drill presses and suit maintenance, fabrication and light industrial applications.

Advantages

The titanium coating increases surface hardness and reduces friction, which helps extend bit life compared with uncoated high-speed steel. A progressive range of diameters from 1.5 mm to 6.5 mm provides flexibility for pilot holes, fastener clearances and precision drilling. The bits are ground to common geometry for efficient chip removal and stable drilling in metal. The set format keeps frequently used sizes together for quick selection on the job.

Suitable for

• Drilling holes in steel, aluminum and non-ferrous metals
• Workshop maintenance and machinery repairs
• Fabrication tasks requiring small to medium diameter holes
• Use with hand drills and bench drill presses

Key specifications

• Material: high-speed steel with titanium coating
• Number of pieces: 13
• Diameter range: 1.5 mm to 6.5 mm
• Intended use: drilling in metal and other hard materials
• Compatibility: standard three-jaw chucks on hand drills and drill presses

How to use

Select the appropriate diameter for the desired hole and secure the bit in the drill chuck. Use a center punch for precise hole location on metal, clamp the workpiece to prevent movement, and apply cutting lubricant when drilling harder metals to reduce heat and wear. Start drilling at moderate speed to establish the hole, then adjust speed according to material hardness and bit diameter. Withdraw the bit periodically to clear chips and allow cooling.

Usage recommendations

For best results when drilling metal, use a cutting fluid or lubricant, keep steady feed pressure without forcing the bit, and match drilling speed to the bit diameter and material hardness. Store the set in a dry place to prevent corrosion and inspect bits for wear before use; replace excessively worn or damaged bits to maintain hole quality and safety.
