A high-performance step drill bit designed for clean, precise hole enlargement in sheet metal, plastic, wood, and other thin materials. Made from heat-treated HSS with a titanium coating, this bit offers 15 steps (2mm increment per step) for versatile hole sizing without the need for multiple drill bits.
Brand: HARDEN
Model: 614132
Type: Step Drill Bit (Unibit / Cone Drill)
Material: High-Speed Steel (HSS), Heat-Treated
Coating: Titanium Nitride (TiN) – Reduces Friction, Increases Durability
Hole Range: 4mm to 32mm (in 2mm increments)
Increments: 15 Steps (2mm per step)
Shank: 3/8" (10mm) Hex Shank for Secure Chuck Grip
Total Length: Approx. 135mm (varies by manufacturer)
Application: Sheet Metal, Plastic, Wood, Drywall, Aluminum
Titanium Coating – extends bit life, reduces heat buildup, and prevents corrosion.
2mm per Step Design – allows precise hole sizing from 4mm to 32mm.
Heat-Treated HSS Construction – maintains sharpness and resists wear.
Hex Shank – prevents slipping in the drill chuck and ensures stable drilling.
Gradual Step Design – reduces burring and provides smooth, clean holes.
Versatile Use – suitable for metal, plastic, wood, and composite materials.
Saves Time & Tools – replaces multiple drill bits for hole enlargement tasks.
