Drill bit STANLEY STA52251 — 15 mm diameter, 165 mm length, 1 pc

STANLEY STA52251 — a single-piece drill bit with a 15 mm diameter and 165 mm overall length designed for general-purpose wood drilling. This mid-sized, straight shank bit is made for use with compatible drills to provide reliable penetration and stable performance during construction, repair and joinery tasks where an extended length and medium diameter are needed.

Advantages

The single-piece construction reduces the risk of breakage at connection points and enhances durability during repeated use. With a 15 mm cutting diameter and 165 mm overall length the bit delivers sufficient reach for through-holes and deeper drilling in timber while maintaining control and accuracy. The straightforward geometry is suitable for easy chip removal in wood and simplifies hole-starting and alignment for common carpentry operations.

Suitable for

• Drilling holes in soft and hardwood for dowels and bolts
• Through-holes in furniture assembly and cabinetry
• Construction site rough carpentry and repair work
• Situations that require a mid-sized diameter with added reach

Key specifications

• Diameter: 15 mm
• Overall length: 165 mm
• Material compatibility: Wood
• Piece count: 1
• Shank type: straight shank (compatible with standard chucks)

How to use

Secure the STA52251 drill bit in the chuck of a compatible drill and tighten the chuck firmly. Mark the drilling point on the wooden workpiece and, if required, use a centre punch or pilot mark to help start the hole. Operate the drill at a speed appropriate for the type of wood—moderate to high speeds for softwoods, moderate for hardwoods—applying steady pressure while keeping the drill perpendicular to the surface. Withdraw the bit periodically for chip clearing on deep holes to avoid clogging and overheating.

Usage recommendations

Wear appropriate eye and hearing protection when drilling. Use clamps or a vise to secure small or thin workpieces. For cleaner finishes, consider backing the workpiece or using a sacrificial board to reduce tear-out at exit points. Inspect the bit for wear before use and replace if the cutting edges are dull or damaged.
