Drill bit set Irwin HSS for metal, cylindrical shank, sizes 1.5–10 mm (multiple sizes) — Irwin 10502500

Set of Irwin HSS drill bits for metal with cylindrical shanks, covering a comprehensive size range from 1.5 mm up to 10 mm and including intermediate sizes for precision work. These high-speed steel bits are designed for drilling various ferrous and non-ferrous metals using standard hand drills and drill presses. The set provides a selection of small diameter to medium diameter bits suitable for tasks that require accurate hole placement and reliable cutting performance in maintenance, fabrication and assembly work.

Advantages

HSS construction offers good hardness and heat resistance for standard metal-drilling applications. The cylindrical shank design ensures compatibility with common chucks in hand drills and bench drills, while the included range of sizes reduces the need to change tools frequently. The set delivers consistent geometry across sizes for predictable drilling behavior and acceptable wear resistance in typical workshop and repair environments.

Suitable for

• Drilling holes in sheet metal, chassis and panels
• Maintenance and repair work on machinery and equipment
• General metal fabrication and assembly tasks
• Use with hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical
• Size range: 1.5 mm up to 10 mm with multiple intermediate sizes (see product listing for complete set)
• Suitable materials: ferrous and non-ferrous metals
• Intended use: drilling with hand drills and drill presses

How to use

Select the appropriate drill bit size for the required hole diameter and secure it in the drill chuck, ensuring the shank is seated straight and tightened. For metal drilling, mark the drilling point, use a center punch if necessary to prevent wandering, and start at low speed to establish the hole. Apply steady pressure and increase speed as appropriate for the material and bit size, using cutting fluid or lubricant to reduce heat and extend tool life. After drilling, clear swarf and inspect the hole for burrs; deburr if needed.

Usage recommendations

Use cutting fluid for improved cooling and chip evacuation when drilling tougher alloys or larger diameters. Maintain correct drill speed and feed—slower speeds for larger diameters and harder metals—to reduce wear and avoid overheating. Store bits in a protective case to keep sizes organized and prevent edge damage.
