Drill bit set STANLEY STA51003 cylindrical universal 1 mm, 2 pcs

Two-piece STANLEY STA51003 drill bit set contains two 1 mm cylindrical universal drill bits designed for precision drilling where very small-diameter holes are needed. The compact set is intended for fine jobs in hobby work, model making, electronics and light workshop tasks. The universal cylindrical shank ensures compatibility with a wide range of hand drills and rotary tools that accept small-diameter bits.

Advantages

The set provides consistent, accurate hole sizes with minimal wandering thanks to the fine 1 mm diameter. Its cylindrical universal shanks make the bits easy to install and remove in chucks that accept round shanks, enabling fast tool changes. The small two-piece selection keeps storage compact and reduces the risk of misplacing bits during detailed work.

Suitable for

• Hobby and model making
• Electronics and PCB drilling
• Fine woodworking and cabinetry details
• Light metal and plastic drilling where a 1 mm hole is required

Key specifications

• Quantity: 2 drill bits
• Diameter: 1 mm
• Shank type: cylindrical universal shank
• Intended use: precision drilling in small-diameter applications
• Typical compatible tools: handheld drills and rotary tools with small-diameter chucks

How to use

Secure the appropriate bit in the chuck or collet of the drill or rotary tool, ensuring the shank is seated straight and tightened to prevent slipping. Use a steady, controlled feed rate and moderate rotational speed appropriate for the material being drilled: lower speeds for metals, medium for plastics, and higher speeds for softer materials. Consider using a center punch or pilot mark on metal and hard plastics to prevent the bit from walking at startup. Apply light cutting pressure and withdraw the bit periodically to clear chips and avoid overheating.

Usage recommendations

For precise results in electronics and model making, use a drill press or a depth stop when possible, maintain clean, sharp bits, and use cutting oil or lubricant when drilling metals to extend bit life.
