Drill bit set AWTools AW41040, pack of 10

AWTools AW41040 drill bit set, pack of 10, contains precision-ground HSS-G (high-speed steel) bits designed for general-purpose metal and plastic drilling. Each bit is double-sided and ground to a 118° point angle to improve centering and reduce walking at the drill entry. The set is supplied as a multiple-pack in a case, offering a convenient quantity for workshops, construction sites, tradespeople, maintenance teams and DIY users who require a reliable assortment of bits for routine drilling tasks.

Advantages

The drill bits are made of HSS-G high-speed steel and precision ground to ensure consistent cutting performance and longer edge life compared with unground drills. The 118° point angle improves centering and reduces the need for pilot holes on many materials. Double-sided grinding provides balanced cutting action and easier resharpening when required. Supplied in a case, the pack of 10 keeps the set organized and protected during storage and transport.

Suitable for

• Drilling alloyed and unalloyed steels
• Working with grey cast iron
• Machining non-ferrous metals (aluminium, brass, copper)
• Drilling plastic components and housings
• General workshop, construction and maintenance tasks

Key specifications

• Material: HSS-G (high-speed steel), precision ground
• Point angle: 118° for improved centering
• Geometry: double-sided ground tips for balanced cutting
• Pack quantity: 10 pieces supplied in a case
• Intended materials: alloyed and unalloyed steel, grey cast iron, non-ferrous metals, plastic

How to use

Secure the appropriate drill bit in the drill chuck, ensuring it is centered and tightened. Select a suitable drilling speed and feed for the material being drilled; lower speeds are recommended for harder steels, higher speeds for non-ferrous metals and plastics. Use cutting fluid or coolant where appropriate when drilling steel or alloyed materials to extend bit life and improve chip evacuation. Apply steady pressure and allow the drill to cut without excessive force; withdraw periodically to clear chips when drilling deeper holes.

Usage recommendations

For best results, match drilling speed to material hardness, use appropriate lubrication when working with steel, and store the bits in the supplied case to protect the cutting edges. When reconditioning, resharpen using standard drill grinding practices for 118° geometry to maintain performance.
