Drill Bit STANLEY STA51098 universal cylindrical 9 mm

STANLEY STA51098 is a 9 mm universal cylindrical drill bit designed for general drilling tasks. The bit features a straight flute and a cylindrical shank that fits standard chucks, allowing use with hand drills and drill drivers. It is intended for drilling into common building materials where a straight, stable bore is required, making it suitable for repair, maintenance and light construction work.

Advantages

The cylindrical shank provides good compatibility with most standard drill chucks and enables quick mounting and secure clamping. The 9 mm diameter offers a balance between precision and efficiency for common fastening and hole-making tasks. The universal design is aimed at reliable performance across a range of everyday materials, reducing the need to change bits frequently during routine jobs.

Suitable for

• Drilling pilot holes for wood screws and anchors
• General maintenance and repair tasks
• Light construction and carpentry work
• Installing fixtures where a straight bore is required

Key specifications

• Diameter: 9 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Intended use: universal/general purpose drilling
• Compatibility: hand drills and drill drivers with standard chucks
• Typical materials: common building materials such as wood, soft plastics and light composite materials

How to use

Insert the cylindrical shank into the drill chuck and tighten securely before operation. Select a suitable drilling speed according to the material: lower speeds for harder materials and higher speeds for softer materials like wood or plastics. Apply steady, even pressure and let the bit cut without forcing; withdraw the bit occasionally when drilling deeper holes to clear debris and reduce heat buildup. After use, clean the cutting edges and store the bit in a dry place to prevent corrosion.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Match drill speed and feed pressure to the material being drilled to extend bit life. For repetitive or heavy-duty drilling, consider periodic sharpening or replacement to maintain hole quality and safety.
