Drill bit STANLEY STA53075 3 mm x 60 mm, single HSS twist drill

STANLEY STA53075 3 mm x 60 mm single HSS twist drill is a straight-fluted high-speed steel drill intended for creating small, precise holes in a variety of materials. With a 3 mm cutting diameter and 60 mm overall length, this HSS bit is compatible with handheld drills and drill presses and is commonly used in repair, assembly and general workshop tasks where accuracy and durability are required.

Advantages

The HSS construction provides heat resistance and wear endurance for repeated drilling at moderate speeds. The 3 mm diameter offers fine, accurate hole making for pilot holes, fastener preparation and delicate machining tasks. Its 60 mm overall length gives adequate working reach while remaining rigid enough to reduce flex and improve hole accuracy when used with the correct speed and clamping.

Suitable for

• Drilling pilot holes for screws and small fasteners
• Precision holes in metal, wood and plastics (material and speed dependent)
• Repair and maintenance tasks in workshops and at job sites
• Use with handheld drills and drill presses for small-diameter holes

Key specifications

• Material: High-speed steel (HSS)
• Cutting diameter: 3 mm
• Overall length: 60 mm
• Design: Single twist drill (straight flute)
• Quantity: 1 piece

How to use

Secure the workpiece properly using clamps or a vice to prevent movement. Fit the 3 mm HSS bit into the drill chuck and tighten firmly. Select an appropriate spindle speed for the material being drilled: higher speeds for wood and plastics, moderate speeds for mild steel. Apply steady, even pressure and allow the drill to cut without forcing; withdraw occasionally to clear chips when drilling deeper holes. Finish by deburring the hole if necessary.

Usage recommendations

For best performance when drilling metals, use cutting oil or lubricant to reduce heat and extend the life of the HSS bit. Match drill speed to material: lower speeds for harder metals, higher speeds for softer materials. Replace worn bits to maintain hole quality and accuracy.
