Hertel SD6560213 Step Drill Bit 13 Sizes 1/8 to 1/2 in

Product Description

The HERTEL SD6560213 is a high-speed steel step drill bit designed to drill 13 incrementally sized holes ranging from 1/8 inch to 1/2 inch in a single tool. Built from M2 high-speed steel with a titanium nitride (TiN) coating, this bit delivers improved wear resistance and longer service life compared to uncoated HSS tools. The concave flute geometry clears chips efficiently during drilling operations. At 2-5/8 inches overall length with a 1/4-inch cylindrical shank and a quick-change configuration, it is suited for use with standard drill chucks and quick-change adapters. Electricians, HVAC technicians, and sheet metal workers rely on this type of bit for clean, single-pass holes in thin materials.

This step drill bit is a general-purpose, multipurpose tool suited for drilling through sheet metal, light-gauge steel, aluminum, plastic, and similar thin materials encountered in residential and light commercial trade work. Each step increment is 1/32 inch, with a step length of 1/8 inch, allowing the technician to drill a precise hole size by stopping at the appropriate step. It is particularly useful when multiple hole diameters are needed on a single job without switching bits.

Key Features

• 13 hole sizes in one bit, ranging from 1/8 inch to 1/2 inch in 1/32-inch increments
• M2 high-speed steel construction for durability in general-purpose drilling applications
• TiN coating increases surface hardness and reduces friction for extended tool life
• Concave flute design promotes efficient chip evacuation during drilling
• Quick-change cylindrical shank with one flat, compatible with standard 1/4-inch chuck systems
• Compact 2-5/8-inch overall length suits tight-space drilling common in panel and enclosure work

Compatibility

Designed as a general-purpose step drill bit compatible with standard 1/4-inch cylindrical shank drill chucks and quick-change bit holders used in hand drills and drill/drivers.

Installation Notes

Step drill bits are installed and operated by electricians, HVAC technicians, plumbers, and sheet metal mechanics. Use appropriate eye protection and secure the workpiece before drilling. Start at low speed and increase as needed to avoid overheating the bit and workpiece. Do not force the bit through material heavier than the rated application; doing so will shorten tool life and may damage the workpiece.
