Product description

The NEO TOOLS HSS step drill bit (conical) covers a range of 4–22 mm in 2 mm steps, so a single tool lets you spot-drill, enlarge and calibrate the hole diameter. The conical geometry with clearly marked numbering makes it easier to control dimensions, and the thin cutting edge at the tip stabilizes the start. The NEO TOOLS tool performs well in mild steel, aluminium, copper and plastics – it is suitable for holes for cable glands, grommets, connector pipes, panel switches or installation components. With a single step drill bit you minimize the number of accessories, save time and maintain repeatability in workshop and service work.

Application

Making and enlarging holes in thin-walled sheet metal and profiles.

Holes for cable glands/cable passages, panel switches, push buttons and stubs in cabinets and enclosures (electrical/automation).

Installation work: pass-throughs in ducts, distribution boxes, enclosures and control panels.

Machining aluminium, mild steel, copper and plastics (sheets, panels, trays).

Quick diameter calibration without changing the tool – drilling + reaming + edge chamfering.

Automotive assembly and servicing: matching holes in covers, brackets, cowl panels.

Production and workshop: serial large-diameter holes in thin components.

Adaptations and repairs in the field: a universal tool for many diameters when changeover speed matters.
