Drill bit STANLEY STA50115 — 1.2 cm diameter, 151 mm length, single piece

Single STANLEY STA50115 drill bit with a 1.2 cm (12 mm) cutting diameter and a total length of 151 mm. This single-piece drill bit is designed for use in standard drills and is intended for drilling tasks in metal; depending on drill speed and technique it can also be used on certain plastics and wood if geometry and coatings permit. Supplied as one unit, the bit fits applications where a 12 mm diameter and extended reach are required for repair, construction and workshop work.

Advantages

The STANLEY STA50115 drill bit provides a precise 12 mm cutting diameter and extended 151 mm overall length for deeper holes or reach into assemblies. Its single-piece supply simplifies inventory and replacement needs. The bit’s design is suitable for standard drill chucks and offers straightforward compatibility with common drill types used in construction and workshop environments. The black finish is practical for identifying the tool in a set and can indicate surface treatment for wear resistance.

Suitable for

• Drilling metal sheets, brackets and structural components
• Creating through-holes where 12 mm diameter is required
• Workshop repairs and general construction tasks
• Applications needing extended reach or deeper holes up to the bit’s length

Key specifications

• Cutting diameter: 1.2 cm (12 mm)
• Overall length: 151 mm
• Quantity: 1 piece
• Primary material suitability: metal (also usable on some plastics and wood depending on drill technique and bit geometry)
• Finish color: black

How to use

Install the drill bit into a compatible drill chuck and tighten securely. Select an appropriate rotation speed and feed rate for the target material: slower speeds and steady pressure for metals, higher speeds for soft plastics or wood if the bit geometry allows. Use cutting fluid or coolant when drilling metals to extend tool life and reduce heat. Clear chips from the hole periodically, and retract the bit occasionally while drilling deep holes to remove debris and prevent binding.

Usage recommendations

For best results when drilling metal, use a suitable lubricant, maintain straight alignment, and operate at recommended speeds for 12 mm bits to reduce wear. Inspect the bit before use for signs of damage and replace if the cutting edge is worn. Store the bit in a dry place to preserve the finish.
