Drill bit set STANLEY STA56010 — 6 pcs HSS-R for metal

The STANLEY STA56010 drill bit set includes six HSS-R (high-speed steel, rolled) bits engineered for drilling into metal. Designed for standard drills and drill drivers, these bits offer durable cutting edges suitable for steel and other ferrous materials. The set is compact and intended for workshop, maintenance and metal fabrication tasks where consistent metal-drilling performance is required.

Advantages

Rolled high-speed steel construction provides toughness and good wear resistance for general-purpose metal drilling. The bits are manufactured to a consistent geometry to ensure reliable cutting action, easier centring and steady feed rates. Compatibility with common drill chucks makes the set versatile for portable and benchtop drilling equipment. The compact 6-piece assortment covers a range of common hole sizes for routine metalwork.

Suitable for

• Drilling holes in mild and medium steel
• Maintenance and repair work in workshops and garages
• Metal fabrication and light fabrication tasks
• Use with standard corded and cordless drills

Key specifications

• Material: Rolled high-speed steel (HSS-R)
• Quantity: 6 pieces
• Intended material: Ferrous metals (steel and similar)
• Compatibility: Standard drill chucks for drill drivers and bench drills
• Typical applications: Through and blind holes in metal sheets and plates

How to use

Select a drill bit size appropriate for the hole required and secure it in the drill chuck. Use a center punch to mark the drilling position on metal to prevent bit walking. Clamp the workpiece or secure it in a vise. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material and bit size. Apply steady pressure and use cutting oil or lubricant for harder steels to reduce heat and extend bit life. Withdraw the bit periodically to clear chips if drilling deep holes.

Usage recommendations

For best results when drilling metal, use a suitable cutting lubricant, maintain moderate drill speeds for larger diameters, and ensure the workpiece is securely clamped. Replace bits when the cutting edge shows visible wear or chattering occurs to maintain hole quality and reduce the risk of breakage.
