Drill Bit AWTools HSS spot-drilled 16 mm, set of 5 (AW41160)

AWTools HSS spot-drilled 16 mm drill bit set, 5 pieces, is intended for general-purpose drilling in metal and other materials where precision and durability are required. Constructed from high-speed steel (HSS) with a spot-drilled (center-cut) point geometry, this set combines wear resistance and improved centering to reduce bit walking at the start of drilling. The five identical 16 mm bits are suitable for both hand drills and drill presses in workshop or industrial environments.

Advantages

The high-speed steel construction provides hardness and heat resistance for prolonged cutting performance and longer tool life under typical drilling conditions. The spot-drilled point reduces lateral slippage on flat or curved surfaces, improving hole accuracy without additional centering operations. Supplied as a set of five, the bits allow quick replacement on repetitive tasks and reduce downtime.

Suitable for

• Drilling holes in mild and alloy steels
• Working with non-ferrous metals such as aluminum and brass
• Drilling some plastics and composite materials
• Use with hand-held drills and small to medium drill presses
• Workshop maintenance and light industrial production tasks

Key specifications

• Material: high-speed steel (HSS)
• Tip geometry: spot-drilled / center-cut point
• Diameter: 16 mm
• Quantity: set of 5 identical drill bits
• Intended use: metalworking and general-purpose drilling

How to use

Select an appropriate cutting speed and feed for the material being drilled and secure the workpiece to prevent movement. Fit the 16 mm HSS bit in the chuck of a hand drill or drill press and tighten securely. For best results on metal, use cutting fluid or lubricant to reduce heat and prolong bit life. Start drilling at low speed to ensure the spot-drilled tip locates the center, then increase speed and apply steady pressure. Withdraw occasionally to clear chips and prevent clogging.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and gloves. Match drilling speed and lubricant to the workpiece material, avoid excessive side loads, and replace bits when wear or chipping reduces performance.
