Drill bit set Top Tools HSS for metal, cylindrical shank, sizes 1.5–13 mm (set 5325)

Top Tools HSS drill bit set for metal with cylindrical shanks covers a continuous range of diameters from 1.5 mm to 13 mm. These high-speed steel bits are intended for drilling into both ferrous and non-ferrous metals and are supplied as a matched set for workshop, maintenance and fabrication applications. The set is suitable for general-purpose metalworking where a selection of small to medium diameters is required and where cylindrical shanks fit standard drill chucks and holders.

Advantages

The HSS construction provides wear resistance and maintains edge hardness at elevated cutting temperatures, offering reliable life when drilling metal. Cylindrical shanks enable secure clamping in standard chucks and hand-held drills without the need for specialized adapters. Having a range of diameters from 1.5 mm to 13 mm in one set reduces tool changeover and ensures availability of common sizes for precision holes in sheet, plate and machined components.

Suitable for

• Drilling holes in ferrous metals such as steel and cast iron
• Drilling in non-ferrous metals such as aluminium, brass and copper
• General workshop and maintenance drilling tasks
• Fabrication and assembly where multiple hole sizes are needed

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical
• Diameter range: 1.5 mm to 13 mm (set of multiple sizes)
• Intended material: ferrous and non-ferrous metals

How to use

Select the drill bit size appropriate for the required hole diameter and clamp the cylindrical shank securely in the drill chuck. Use a drilling speed appropriate for the metal being worked—lower speeds for harder materials and higher speeds for softer non-ferrous metals—while applying steady, controlled feed pressure. Apply cutting fluid or lubricant when drilling harder alloys or thicker sections to reduce heat and improve tool life. Withdraw the bit periodically to clear chips when drilling deep holes.

Usage recommendations

For best results, match drill speed and feed to the workpiece material and keep the drill bit sharp; replace worn bits to maintain hole accuracy and surface finish. Wear appropriate eye and hand protection during operation and secure workpieces to prevent rotation or movement.
