Drill bit set AWTools AW35119BL — 15 pieces, total weight 825 g

The AWTools AW35119BL drill bit set includes 15 pieces and weighs a total of 825 g. Made of hardened and tempered S2 tool steel, the set comprises spline bits in two lengths and an adapter for broad compatibility. Stored in a metal case, the assortment is intended for drilling and screw-driving tasks with both hand and power tools and is suitable for workshop, construction, maintenance and automotive applications.

Advantages

The bits are manufactured from S2 tool steel that has been hardened and tempered to provide increased wear resistance and torsional strength. The set includes the most commonly used spline sizes in short (30 mm) and long (75 mm) formats, allowing access in confined spaces and extended reach where needed. A 1/2" adapter for 10 mm bits enhances compatibility with a range of drivers and impact tools. The metal case protects the bits during storage and transport and keeps the assortment organised.

Suitable for

• General-purpose drilling and screw-driving with spline fasteners
• Car repair workshops and automotive servicing
• Construction, installation and maintenance tasks
• Hand tool and power driver use, including impact drivers

How to use

Select the spline bit that matches the fastener size, insert it into the adapter or compatible chuck, and secure it in the driver. For hand tool use, fit the bit into the screwdriver or handle; for power tools, ensure the driver is set to the correct torque and speed for the fastener and material. Use short (30 mm) bits for close access work and longer (75 mm) bits where extra reach is required. Store bits in the metal case after use to protect cutting edges and prevent loss.

Usage recommendations

When using the set with impact drivers or high-torque tools, confirm bit seating and tool settings to reduce the risk of stripping fasteners or damaging bits. Match spline size precisely to the fastener and avoid excessive side load to prolong bit life. Keep bits dry and clean; apply light lubrication to fasteners where appropriate for smoother operation.
