Drill bit YATO 22612 — single piece, Sthor 22612

Single-piece drill bit YATO 22612 — single piece, Sthor 22612 is a single-unit step drill bit supplied as one piece per pack. It is intended for use with compatible electric or hand drills for general drilling tasks and for creating stepped holes in thin materials. The bit is made of high-speed steel with a titanium nitride coating and has a cylindrical shank, making it suitable for replacement of a worn bit or for occasional repair and DIY jobs.

Advantages

The stepped geometry allows drilling multiple hole diameters with a single bit, reducing the need to change tools during work. Titanium nitride coating increases surface hardness and improves wear resistance, while the HSS core provides strength and toughness. The design promotes clean hole edges with reduced burr formation and features self-centering characteristics on rounded and slippery surfaces. Fast heat dissipation helps maintain cutting performance when working with harder materials.

Suitable for

• Drilling holes in stainless and structural steel sheets
• Working with cold-rolled steel and non-ferrous metals
• Creating stepped holes in plastic components
• Small repair, maintenance and DIY tasks

Key specifications

• Type: step (stepped) drill bit
• Material: high-speed steel (HSS) with titanium nitride coating
• Shank: cylindrical shank
• Step increment: steps in 2 mm increments
• Suitable materials: stainless steel, structural steel, cold-rolled steel, non-ferrous metals, steel sheets, plastics
• Quantity: single-piece — one drill bit per pack

How to use

Secure the drill bit in the drill chuck with the cylindrical shank fully seated and tightened. Select an appropriate drilling speed for the material being worked on; lower speeds are recommended for harder metals and higher speeds for plastics. Apply steady, moderate pressure and allow the bit to cut without forcing. Use cutting lubricant when drilling metals to reduce heat and extend tool life. After use, clean chips from the flutes and store the bit in a dry place.

Usage recommendations

For best results when drilling metals, use cutting oil and moderate feed rates; for plastics, use higher speeds and minimal pressure to prevent melting. Inspect the bit before use and replace it if wear or damage is evident to maintain clean hole edges and safe operation.
