# GARHWAL 80 mm Bi-Metal Hole Saw

GARHWAL’s 80 mm bi-metal hole saw is listed for cutting wood, plasterboard, plastic and thin metal, with an arbor and pilot bit claimed for the kit. Its stated 30mm cutting depth and reports of cores sticking or the drill bit snapping are worth weighing before choosing it for repeated or demanding work.

## At a glance

- The 80 mm size is intended for larger openings such as ceiling lights, vents and speakers, according to the listing.
- A spring is claimed to push the cut-out disc out after drilling, while knock-out holes are also mentioned for core removal.
- The listing describes variable-pitch teeth and a bi-metal construction.

## Pros

- One stated diameter and a listed 30mm cutting depth suit projects that need a broad opening rather than a small pilot hole.
- The listing claims an included arbor and pilot bit, and compatibility with bench, electric and hand drills.
- Core-ejection features are described, which may help when removing cut material between holes.

## Cons

- Customer feedback reports drill bits snapping and cut wood getting stuck inside the saw, which may disrupt use and raise durability concerns.
- Customers disagree about sharpness, so cutting performance may not be consistent across experiences.

## Before you buy

- The manufacturer advises adult use, appropriate safety gear, positioning the saw before starting the drill, not starting it against the material, and waiting for it to stop before withdrawing.
- Listing details are inconsistent: the title and feature claims specify an 80 mm bi-metal saw with arbor and pilot bit, while the details list High Speed Cobalt, dimensions of 8L x 8W centimetres, and an item thickness of 38 Millimetres. A separate product description states 30mm cutting depth. The exact material specification and the relationship between these measurements are not confirmed. The listing claims the arbor and pilot bit, but no explicit package inventory is supplied.

## A good fit for

- DIY users making 80 mm openings in listed materials such as wood, drywall, plastic or thin metal.
- Projects such as ceiling-light, air-duct or speaker openings where the claimed arbor and pilot bit are useful.

## Less suited to

- Buyers who need dependable evidence of durability for frequent or heavy-duty use, given reports of drill-bit breakage.
- Work requiring a confirmed material specification or cutting depth beyond the listing’s stated figures.

## Customer feedback

Customer feedback reports that the saw cuts materials including plasterboard and 25mm hardwood, with functionality and value also mentioned positively. There are concerns about drill-bit breakage and wood sticking in the cutting disc, while sharpness receives mixed comments. For projects using the listed 80 mm size, these reports make suitability for occasional cutting more plausible than relying on it for repeated demanding work. The positive overall rating does not establish how it will perform in a particular material or drill setup.
- Positive themes: Customers report cutting performance through plasterboard and 25mm hardwood.
- Positive themes: Customers mention functionality and value positively.
- Negative themes: Customer feedback raises concerns about drill-bit breakage.
- Negative themes: Customers report wood sticking inside the cutting disc.
- Mixed feedback: Feedback on sharpness is divided, with some finding it sharp and others saying it is not sharp enough.
