NEIKO Step Drill Bit, 7/8-Inch to 1-1/8-Inch
Product description
A hole that needs to be enlarged can turn into a bit-swap chore, especially when you’re working with sheet material. This NEIKO step drill bit is designed to cut at two stated sizes, 7/8 and 1-1/8 inches, so you can move from one diameter to the other with the same bit.
Its 1/4-inch quick-change hex shank is made for faster swaps between compatible chucks and impact drivers.
Getting the most from it
This bit is aimed at jobs where you need one of its stated diameters in materials such as sheet metal, aluminum, copper, wood, or plastic. For example, at a workbench you could drill a smaller opening in a sheet-metal panel, then continue to the larger step if the fitting or pass-through needs more clearance. The engraved size markings are intended to make it easier to identify the step while you work.
The 135-degree split-point tip is designed to help the bit start without wandering off the intended center. Its two-flute straight-groove design is meant to lift chips and reduce chatter, according to the maker, it also helps deburr as the hole is enlarged. Keep in mind that results depend on the material and how the bit is used. The listing does not provide recommended speeds or material thickness limits, so this is not a setup guide for every drilling job.
Why it’s worth it
The appeal is straightforward: a stepped bit can handle two hole diameters without reaching for a second bit mid-task. The quick-change shank also suits a workflow where you switch bits frequently, rather than stopping to tighten a conventional drill chuck. You’ll appreciate it if you often make or enlarge holes in sheet goods and want the two stated sizes within reach.
There is a practical trade-off. This is a focused two-step tool, not a broad graduated bit with a long run of hole sizes. If you prioritize quick changes and those particular diameters, it has a clear role, if you prefer more size choices from one bit, a model with more steps would be a better fit. It may not suit you if your work routinely calls for diameters outside the sizes listed here.
At a glance
- Type: Two-step drill bit
- Material: #4241 high-speed steel with titanium nitride coating
- Stated hole sizes: 7/8 and 1-1/8 inches
- Shank: 1/4-inch quick-change hex
- Tip and flutes: 135-degree split point, two-flute straight-groove design
- Listed materials: Steel and other sheet metal, aluminum, copper, wood, and plastic
The coating and HSS construction are intended for durability, but the product information does not establish a service life or make it suitable for every kind of metal. For tougher or more specialized work, match the bit to the material and the hole size rather than assuming one step bit covers every need.
Final verdict
This NEIKO bit makes the most sense when your work regularly calls for 7/8- or 1-1/8-inch holes and you value a quick-change shank. It offers a more compact approach than carrying separate bits for those two sizes, while its split point and fluted design are aimed at cleaner starts and chip removal. Choose a more versatile multi-step bit if you need a wider range of diameters, choose this one when its specific sizes match the job.
