Drill bit STANLEY STA58500 triangular cutting 4 mm

STANLEY STA58500 triangular cutting 4 mm is a drill bit engineered for light-duty drilling and repair work. With a 4 mm diameter and a triangular cutting profile, this bit is intended for use with hand drills and drill drivers that accept standard shank sizes. The design promotes stable penetration and controlled chip removal when used in compatible materials, providing a compact solution where precise small-diameter holes are required.

Advantages

The triangular cutting geometry improves bit stability during drilling and helps maintain a straight bore. The 4 mm diameter is suited to tasks that require small, accurate holes while the standard shank ensures compatibility with a wide range of hand drills and drill drivers. The bit's profile supports controlled chip evacuation to reduce clogging and to keep cutting forces consistent for light-duty applications.

Suitable for

• Drilling small diameter holes in wood, plastics, and light composite materials
• Repair and maintenance tasks requiring precise 4 mm holes
• Use with portable hand drills and cordless drill drivers
• Prototyping and DIY projects where compact drill bits are needed

Key specifications

• Diameter: 4 mm
• Cutting profile: triangular
• Intended tool type: hand drills and drill drivers with standard shank acceptance
• Application level: light-duty drilling and repair work
• Typical materials: wood, plastics, light composites

How to use

Select a compatible hand drill or drill driver and secure the drill bit in the chuck, ensuring firm clamping of the standard shank. Mark the drilling point, set an appropriate speed for the material, and apply steady, moderate pressure while drilling. Allow the bit to work without excessive force to maintain hole accuracy and to prevent bit wandering. Withdraw the bit periodically if necessary to clear chips and avoid overheating.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drilling speed and feed to the material to extend bit life, and avoid applying excessive lateral force. For harder materials or heavy-duty tasks, choose a specialized bit designed for higher loads.
