4-20mm HSS-G M2 Tin-Coated Spiral Step Drill
The KAMTEC HSS-G TiN Coated Spiral Step Drill (4–20mm) is engineered for fast, precise drilling across multiple materials using a single bit. It drills a wide range of diameters with one tool, reducing tool changes and improving efficiency on site. The spiral step design enhances cutting stability and control, delivering clean, accurate holes without pre-drilling—ideal for sheet materials and trade applications.
Manufactured from high-quality HSS-G (M2) steel and finished with a TiN (Titanium Nitride) coating, it offers increased durability, reduced friction and faster cutting performance. The self-starting tip eliminates the need for a centre punch, while the progressive 4–20mm sizing provides maximum versatility across a broad range of applications. Supplied in individual blister packaging for easy retail display and storage.
