A professional 3-piece step drill bit set designed for imperial/inch-sized hole drilling and enlargement in sheet metal, plastic, and wood. Made from heat-treated HSS with titanium coating, this set provides clean, precise holes for electrical, plumbing, automotive, and general fabrication work.
Brand: HARDEN
Model: 614173
Type: Step Drill Bit Set (3 Pieces, Inch Sizes)
Material: High-Speed Steel (HSS), Heat-Treated
Coating: Titanium Nitride (TiN) – Reduces Friction, Extends Life
Shank: Hex Shank (Secure Chuck Grip)
Application: Sheet Metal, Plastic, Wood, Aluminum, Thin Materials
Bit 1: 3/16" – 1/2" Step Drill
Covers small to medium holes; ideal for electrical boxes, conduit, and light-duty tasks.
Bit 2: 1/4" – 3/4" Step Drill
Versatile mid-range bit; suitable for plumbing pipes, HVAC vents, and fabrication.
Bit 3: 1/8" – 1/2" Step Drill
Fine-step bit for precision small holes; perfect for thin sheet metal, enclosures, and DIY projects.
(Exact step increments may vary; typically includes multiple intermediate sizes within the range.)
Titanium Coating – reduces heat buildup, increases durability, and prevents rust.
Heat-Treated HSS Construction – ensures long-lasting sharpness and strength.
Hex Shank – prevents slipping in the drill chuck for safer, more stable drilling.
Gradual Step Design – produces smooth, burr-free holes with clean edges.
Complete Inch Size Coverage – handles a wide range of imperial drilling needs.
Time & Tool Saver – eliminates the need for multiple drill bits in common sizes.
Ideal for:
Electrical work (panel knockouts, conduit holes)
Plumbing (pipe installations, drainage holes)
Automotive (sheet metal, body repair, modifications)
HVAC (duct holes, vent openings)
Metal fabrication and welding projects
DIY home improvement and crafts
Appliance repair and maintenance
