Drill bit STANLEY STA53105 — 7 mm diameter, 100 mm length, single piece

Single 7 mm drill bit by STANLEY designed for standard drilling tasks. With an overall length of 100 mm, this replaceable drill bit fits most electric and cordless drills and is intended for use in masonry, as well as for drilling in metal, wood and some plastics when appropriate drill speed and feed are used. Supplied as a single piece, it is suitable for repair work, installations and general DIY drilling jobs.

Advantages

The drill bit combines a straightforward geometry and consistent diameter for accurate holes. Its 100 mm length provides extended reach for deeper holes or applications where access is limited. Compatibility with common drill chucks makes it easy to install and replace, while the single-piece supply ensures you get exactly the size needed for specific tasks.

Suitable for

• Drilling into masonry (concrete, brick, block)
• General metal drilling with appropriate speed and lubrication
• Woodworking and carpentry drilling tasks
• Light plastics where chip evacuation and speed are controlled
• Home repairs, installations and mounting fixtures

Key specifications

• Diameter: 7 mm
• Overall length: 100 mm
• Suitable materials: masonry, metal, wood, some plastics (depending on drill settings)
• Pack quantity: 1 piece

How to use

Install the 7 mm drill bit in a compatible drill chuck and tighten securely. Select an appropriate drill speed and feed for the material: lower speeds for metal, medium to high speeds for wood and adjusted speeds for plastics to avoid melting. For masonry use, employ a hammer/drill function where applicable and apply steady pressure with periodic withdrawal to clear dust. Use cutting fluid or lubrication for harder metals to extend bit life. After drilling, inspect the hole and deburr edges if needed.

Usage recommendations

Wear appropriate eye and hand protection during drilling. For masonry, use a drill with hammer action and select drill speeds recommended for the material. Replace the bit when wear or dullness reduces drilling performance to maintain hole quality and prevent damage to workpieces.
