Drill bit STANLEY STA50085 8 mm x 117 mm, single-piece

STANLEY STA50085 8 mm x 117 mm single-piece drill bit is designed for routine drilling tasks. With an 8 mm diameter and 117 mm overall length, this single-piece bit is supplied individually and intended for use with compatible drills. It is presented in a dark finish and is suitable for general-purpose drilling in common workshop and construction environments depending on the material and drill used.

Advantages

The single-piece construction provides straightforward mounting and stable rotary motion when used in an appropriate drill chuck. Its 8 mm diameter offers a standard size for a variety of fixing and installation tasks, while the 117 mm length gives reach for through-holes and thicker workpieces. Being supplied as one piece makes it easy to replace and carry as a spare for on-site repairs or installations.

Suitable for

• Drilling holes for fasteners and anchors in metal where appropriate cutting speed and coolant are used
• Routine maintenance and repair tasks requiring an 8 mm hole
• Installation jobs where a compact, single-bit solution is needed

Key specifications

• Diameter: 8 mm
• Overall length: 117 mm
• Material suitability: metal (use appropriate speeds and cooling/lubrication)
• Finish: black
• Quantity: 1 piece

How to use

Select a drill with a compatible chuck and firmly secure the 8 mm bit. Set the drill speed and, if drilling metal, apply suitable cutting fluid or coolant to reduce heat and prolong tool life. Begin drilling with light axial pressure until the bit locates, then apply steady pressure through the cut. Retract periodically when drilling deep holes to clear chips. After use, clean chips from the flutes and store the bit in a dry place to prevent corrosion.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For metal drilling, choose correct rotational speed and employ cutting fluid; ensure the workpiece is clamped securely before drilling. Inspect the bit for wear or damage before use and replace if worn to maintain hole quality and safety.
