HSS Bits Tivoly 18-Piece for Steel 10mm Max 2mm Min

The Tivoly High-performance HSS drill bit set (18 pieces) is designed for fast and intensive drilling in high-strength steels and cast irons. The set covers diameters from 2 mm up to 10 mm and features a specialised drill geometry with FUSIO coating to improve wear resistance and cutting performance.

Advantages

The FUSIO coating combined with HSS material and optimised geometry enables increased durability and consistent drilling speed in demanding metalworking applications. Automatic centring and a 135° tip angle ensure accurate starts and reduced walking, while fluted design improves chip evacuation and stability during use.

Suitable for

• Drilling holes in high-strength steel
• Working with cast iron
• General metal fabrication and maintenance tasks
• Professional and workshop use requiring diameters from 2 mm to 10 mm

How to use

Select the appropriate drill diameter for the hole required, secure the workpiece, and use an appropriate drill chuck and speed for HSS bits. Start drilling with light pressure to allow the 135° tip and automatic centring to locate the hole, then apply steady pressure and suitable cutting fluid when working on steels and cast irons to prolong bit life and improve chip removal.

Usage recommendations

Use cutting lubricant for drilling high-strength steels, keep drilling speeds moderate for larger diameters, and replace bits when wear or chipping appears to maintain hole quality and operator safety.
