Drill bit STANLEY STA52021 7 mm x 110 mm, single piece

STANLEY STA52021 drill bit, 7 mm diameter and 110 mm overall length, is a single-piece metal bit designed for general-purpose drilling in wood and similar materials. Supplied as one piece, this 7 mm x 110 mm bit fits standard chucks and is intended for use with power drills for repair, construction and DIY tasks where a clean, consistent 7 mm hole is required.

Advantages

The single-piece construction provides rigidity and reduces the risk of breakage under normal operating conditions. A 7 mm cutting diameter delivers consistent hole size for dowels, fasteners and through-holes. The 110 mm overall length gives sufficient reach for many common woodworking and installation tasks while remaining compatible with most handheld and bench drills. The bit is manufactured by a recognized tool brand and is supplied individually for single-use replacement or for building a custom set.

Suitable for

• Drilling pilot and through-holes in soft and medium-density wood
• Creating holes for dowels, screws and plastic anchors in wooden substrates
• General repair, joinery and furniture assembly tasks

Key specifications

• Diameter: 7 mm
• Overall length: 110 mm
• Material compatibility: wood and similar timber-based materials
• Quantity: single piece

How to use

Install the 7 mm drill bit into the drill chuck and tighten securely. Select an appropriate drilling speed for the material—moderate to high speed for softwoods, moderate speed for hardwoods—and apply steady axial pressure. Keep the drill perpendicular to the work surface to ensure a straight hole. For through-holes, back the drill out occasionally to remove chips; for clean entry and exit, consider using a backing board. Wear appropriate eye and hand protection while drilling.

Usage recommendations

Use lubrication or reduced speed for prolonged drilling in hardwood to reduce heat buildup; replace the bit if it becomes dull or damaged to maintain hole quality and operator safety.
