## Summary description

Step twist drill bit AWTools model 1077302 made from M2 high-speed steel with TiAlN coating. Designed for stepped hole drilling across a range of diameters from 4 mm to 52 mm in progressive increments. Suitable for use with hand-held drills and drill presses on sheet metal, thin plates and similar materials where variable diameters are required.

## Long description

The AWTools Step Twist Drill Bit model 1077302 is a stepped drill bit made from M2 high-speed steel with a TiAlN (titanium aluminum nitride) coating. It is engineered for producing stepped holes with diameters ranging from 4 mm to 52 mm in progressive increments. Suitable for use in both hand-held drills and drill presses, this stepped bit is intended primarily for sheet metal, thin plates and similar materials where multiple diameters are required from a single tool.
Advantages
The M2 high-speed steel core provides toughness and wear resistance, while the TiAlN coating increases surface hardness, heat resistance and friction reduction during cutting. The stepped geometry allows efficient drilling of multiple diameters without changing tools, saving time and maintaining concentricity between hole steps. Compatibility with common drilling machines makes it a flexible option for workshop and onsite use.
Suitable for
Drilling stepped holes in sheet metal and thin metal plates
Creating variable-diameter holes for grommets, cable pass-throughs and fittings
Prototype work and small-batch fabrication where multiple diameters are needed
Onsite repairs and installations using hand-held drills or drill presses
Key specifications
Material: M2 high-speed steel (HSS)
Coating: TiAlN (titanium aluminum nitride)
Diameter range: stepped from 4 mm up to 52 mm
Design: step twist geometry for progressive hole sizes
Suitable machines: hand-held drills and drill presses
Recommended application materials: sheet metal, thin plates and similar metals
How to use
Secure the workpiece and mark the drilling position. Select appropriate rotational speed and feed for the material thickness and type; lower speeds and steady feed are recommended for larger diameters. Use proper clamping to avoid movement, and apply cutting fluid if drilling thicker or harder metals to reduce heat and improve tool life. Start drilling at a controlled feed until the smallest step is formed, then continue smoothly through each subsequent step until the final diameter is reached. Withdraw the tool periodically to clear chips if necessary.
Usage recommendations
For best results, use steady, moderate speeds and maintain consistent feed pressure. Apply cutting fluid when drilling harder alloys or extended runs. Inspect the bit for wear and recoat or replace when cutting becomes less efficient to preserve hole quality and concentricity.
