Drill bit STANLEY STA53125 — diameter 12 mm, length 150 mm, 1 pc

STANLEY STA53125 drill bit is a single-piece solid cylindrical bit with a 12 mm cutting diameter and a 150 mm overall length. Designed for general-purpose drilling tasks, this drill bit fits standard chucks and is suitable for use with handheld and bench drills. The bit’s dimensions offer a balance between reach and rigidity, making it appropriate for routine repair, construction and workshop applications when used with the correct drill type and speed.

Advantages

The 12 mm diameter delivers a clean, consistent hole size for dowels, through-holes and fixings. At 150 mm length the bit provides extended reach for deeper drilling while maintaining sufficient rigidity for accurate drilling. As a single-piece unit, it reduces the risk of joint failure and simplifies replacement. Compatibility with common drill chucks makes it versatile across a range of drilling tools.

Suitable for

• Drilling holes in wood for dowels, screws and fittings
• Through-holes in plastic components and panels
• Light metal drilling when using an appropriate drill and feed rate
• General repair, construction and workshop tasks requiring a 12 mm hole

Key specifications

• Cutting diameter: 12 mm
• Overall length: 150 mm
• Quantity: 1 piece
• Shank type: cylindrical (compatible with standard chucks)
• Material and tip geometry: suitable for general-purpose drilling (wood, plastics, light metals depending on drill and speed)

How to use

Secure the drill bit firmly in the drill chuck and tighten according to the drill manufacturer’s instructions. Select a drill speed and feed appropriate to the work material: lower speeds for metals, moderate speeds for plastics, and higher speeds for most woods. Mark the drilling point, support the workpiece to prevent movement, and start drilling with steady pressure. Withdraw the bit occasionally to clear chips when drilling deep holes, and use cutting fluid where applicable for metal work.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves) and clamp workpieces. Match drill speed and feed to the material to extend bit life. Replace the bit if signs of wear or damage appear to ensure clean holes and safe operation.
