Hertel SD6560619 Step Drill Bit 13-step Hss

Product Description

The HERTEL SD6560619 is a 13-step high-speed steel step drill bit designed for multipurpose hole-making in a single tool. Built from M2 HSS with a black oxide finish, it bores 13 hole sizes ranging from 1/8 inch up to 1/2 inch in 1/32-inch increments. The cylindrical quick-change shank measures 1/4 inch in diameter, and the overall tool length is 2-5/8 inches. A concave flute geometry channels chips away from the cutting zone, helping maintain clean entry and consistent step depth. Electricians, HVAC technicians, and plumbers reach for step bits when punching knockouts, conduit holes, or sheet-metal openings without swapping drill bits between sizes.

The SD6560619 fits general-purpose trade applications where sheet metal, thin steel, aluminum, plastic, or similar materials need multiple hole diameters in one session. Each step is 1/8 inch long, giving the operator a clear stopping shoulder at every increment. The black oxide coating provides mild corrosion resistance and reduces friction during cutting. A single flat on the cylindrical shank prevents bit slippage in standard three-jaw and quick-change chucks. This bit is sold individually and is well suited for service vans and job boxes where compact tooling is a priority.

Key Features

• 13 hole sizes from 1/8 inch to 1/2 inch in 1/32-inch step increments
• M2 high-speed steel construction for durability across general-purpose materials
• Black oxide finish for reduced friction and mild corrosion resistance
• Concave flute design promotes chip evacuation during drilling
• 1/4-inch cylindrical quick-change shank with one flat for secure chuck grip
• Compact overall length of 2-5/8 inches suits tight-access drilling situations

Compatibility

Designed as a general-purpose step drill bit compatible with standard 3-jaw keyed and keyless drill chucks as well as quick-change chuck systems that accept 1/4-inch cylindrical shanks.

Installation Notes

Step drill bits are typically used by licensed electricians, HVAC technicians, and plumbers working with sheet metal, electrical enclosures, and thin-gauge panels. Always center-punch the work surface before drilling to prevent bit walking. Use appropriate eye protection and secure the workpiece firmly before applying power. Keep drilling speed appropriate for the material being cut to preserve cutting edge life and step geometry.
