Drill bit set Tvardy T02001 HSS for metal 19 pcs 1.0–10.0 mm

Tvardy T02001 HSS for metal 19 pcs 1.0–10.0 mm is a set of high-speed steel drill bits intended for drilling steel and non-ferrous metals. The set includes 19 sizes that span from 1.0 mm to 10.0 mm, covering common small and medium diameters used in workshop and industrial applications. HSS material provides increased wear resistance and heat tolerance compared with carbon-steel bits, enabling repeated use in hand-held drills and drill presses for metalworking tasks.

Advantages

The HSS construction offers a balance of hardness and toughness for reliable cutting performance on ferrous and non-ferrous metals. A comprehensive size range reduces the need to change sets when working on varied hole diameters. The set is suitable for use in both portable drills and bench or pillar drills, maintaining dimensional accuracy and edge retention under moderate drilling speeds and pressures.

Suitable for

• Drilling holes in mild and alloy steels
• Working with aluminum, brass and other non-ferrous metals
• Prototype, maintenance and repair tasks in workshops
• Hand-held drilling and drill-press operations

Key specifications

• Material: High-speed steel (HSS)
• Number of pieces: 19
• Diameter range: 1.0 mm to 10.0 mm
• Intended material: Steel and non-ferrous metals
• Application: Hand-held drills and drill presses

How to use

Select the required drill diameter from the set and secure the workpiece to prevent movement. Use a suitable drill bit holder or chuck and set the drill speed according to the material and bit size — lower speeds for larger diameters and harder steels, higher speeds for small diameters and softer non-ferrous metals. Apply steady feed pressure and use cutting fluid or coolant when drilling steel to reduce heat and extend bit life. Withdraw the bit periodically to clear chips and avoid clogging.

Usage recommendations

For best results, start with a pilot or center punch mark to reduce wandering, use appropriate cutting fluid for steel, and store bits in their original case to protect tips. Avoid excessive speed and pressure to prevent premature wear or breakage of small-diameter bits.
