Drill bit AWTools AW41340, pack of 10 pieces

AWTools AW41340 drill bit pack of 10 pieces contains high-speed steel (HSS) twist drills with a precision-ground flute and a cylindrical shank designed for standard drilling tasks. Each lightweight bit delivers consistent cutting performance and is built to meet DIN 338 dimensions, making it compatible with a wide range of chucks and holders. The set format provides spare bits for workshop, construction or home maintenance projects where a longer reach and reliable hole quality are required.

Advantages

Manufactured from HSS high-speed steel and precision ground for accurate cutting geometry, these drill bits offer durability and clean chip evacuation. The cylindrical shank allows quick and secure clamping in most drill chucks. Their longer flute length is suited to drilling deep holes while maintaining stability, and compliance with DIN 338 ensures predictable fit and interchangeability with other standard tooling.

Suitable for

• Drilling alloyed and unalloyed steels
• Working with gray cast iron
• Drilling non-ferrous metals such as aluminum and copper
• Drilling plastics and composite materials
• Professional workshop, construction sites, and home improvement tasks

Key specifications

• Material: HSS high-speed steel, precision ground
• Shank type: cylindrical shank for standard drill chucks
• Standard: manufactured to DIN 338 dimensional specifications
• Application: suitable for deep hole drilling and extended reach tasks
• Recommended workpieces: alloyed/unalloyed steel, gray cast iron, non-ferrous metals, plastics
• Pack contents: 10 identical drill bits

How to use

Choose a drill speed appropriate for the workpiece material and secure the bit in the drill chuck by tightening evenly around the cylindrical shank. Position the drill perpendicular to the work surface, start at low speed to establish a pilot groove, then increase speed and apply steady pressure. For deep holes, periodically withdraw the bit to clear chips and prevent overheating. Use cutting fluid when drilling steel or other metals to extend tool life and improve hole quality.

Usage recommendations

For best results, match drill speed and feed to the material: moderate speeds and cutting fluid for steels, higher speeds for non-ferrous metals and plastics. Inspect bits for wear before use and replace when cutting performance deteriorates. Store the pack in a dry place to prevent corrosion and keep spare bits organized for quick replacement on the job.
