Product Attributes
Memo
This ORMADUS® step drill features a spiral flute geometry and gold TiN (Titanium Nitride) coating, covering 6 incremental hole sizes from 1/16″ up to 1/2″. The hex shank prevents slippage within drill chucks for stable operation.
Spiral flutes facilitate efficient chip evacuation, reducing heat buildup and delivering smoother, cleaner holes compared with straight-flute step drills. The TiN coating lowers friction, improves wear resistance and extends tool service life. One single drill can produce multiple hole diameters, eliminating frequent bit changes during fabrication and maintenance work.
Typical Applications
Hole drilling in thin sheet metal, stainless steel, aluminum, plastic, and wood. Widely used for electrical work, metal fabrication, HVAC, and field maintenance.
Notes
Recommended for use with cutting fluid when drilling metals, especially stainless steel. Best suited for thin workpieces; avoid heavy pressure to prevent workpiece deformation.
