## At a glance

- Two cutting edges and a balanced double flute are designed to support cutting and manage chatter and vibration.
- The listing describes use in high- and low-speed cordless drill modes.
- Intended for common step-drill tasks such as conduit openings, electrical knockouts and faucet installations.
- Manufacturer claims include cleaner holes and up to 2X more holes per battery charge. These are stated performance claims, not independently verified results.

## Pros

- The title-stated 3/16 to 7/8 inch range suits a variety of common hole sizes with one bit.
- The listed applications span metal, plastics and other materials, including electrical and plumbing tasks.
- The two-flute design and cordless-drill focus make it relevant for mobile trade work.

## Cons

- This is a single bit, so the listed size range does not provide a multi-bit set for other diameter ranges.

## Before you buy

- Listing details are inconsistent: the title gives a 3/16 to 7/8 inch range, while the cutting-diameter field says 2 inches and the minimum bore is 0.19 inches. Confirm the intended step sizes before purchase. The listing also calls the flute straight while describing it as Curved-Tec elsewhere. Material use is stated for thicknesses up to 1/8 inch, and performance statements such as up to 2X more holes per charge are manufacturer claims.

## In the box

## A good fit for

- Electricians and contractors needing step-drilled openings for conduit or knockouts in listed materials.

- Work involving sheet metal, steel, copper, brass, aluminum, plastics or other listed materials within the stated thickness limit.

- Applications requiring material thicker than the stated limit of 1/8 inch.

## Customer feedback

Aggregate customer ratings lean positive, with most ratings in the top category, but a smaller share are low ratings. Without written feedback, the reasons behind either response are unknown. For buyers relying on the advertised hole range or cordless performance, the listing's conflicting diameter details make confirming the size steps especially important.
