Drill Bit Set Makita P-60274-10 HSS-G for Metal 5.0 mm DIN 338 (10 pcs)

Makita P-60274-10 is a set of ten HSS-G (high-speed steel ground) drill bits with a 5.0 mm diameter produced to DIN 338 standards. These drill bits are intended for drilling steel and other ferrous materials and feature a precise conical point geometry that facilitates accurate centring and consistent chip evacuation. The set is suitable for both handheld and machine drilling in workshop, maintenance and fabrication environments where straight drilling and diameter accuracy are required.

Advantages

The HSS-G material provides a balance of hardness and toughness suitable for drilling unalloyed and low-alloy steels. DIN 338 ground geometry ensures straightness and concentricity, which reduces wobble and improves hole quality. The 5.0 mm diameter is a common size for general metalworking tasks, and the ten-piece quantity supports repeated use or replacement during projects. These bits are compatible with standard drill chucks and are ready for immediate use in manual and powered drilling equipment.

Suitable for

• Drilling holes in mild and low-alloy steel
• Workshop and maintenance repair tasks
• Machine drilling on drill presses and CNC machines for metalworking
• Handheld drilling with corded or cordless drills

Key specifications

• Bit material: High-speed steel (ground)
• Diameter: 5.0 mm
• Quantity: 10 pieces per set
• Point geometry: Conical/standard 118°-type ground point (DIN 338 geometry)
• Intended materials: Steel and other ferrous materials
• Compatibility: Standard cylindrical shank suitable for common drill chucks

How to use

Select the 5.0 mm drill bit from the set and secure it in the drill chuck, ensuring correct axial alignment and tight clamping. Mark and centre-punch the drilling location on the workpiece to improve accuracy. Use appropriate cutting speed and feed for steel, apply steady pressure and ensure proper cooling or cutting fluid as needed to reduce heat and extend tool life. Clear chips regularly and pause drilling if necessary to prevent overheating. After use, clean the bits and store them in their case to protect the ground edges.

Usage recommendations

If drilling steel, start with a moderate speed and use cutting fluid for prolonged life of the HSS-G bits. For precision holes, centre-punch before drilling and use a drill press where possible to maintain perpendicularity and repeatability.
