## Description

What are the hole saws used for? They are used to cut perfectly round holes in a wide variety of materials. Widely used in plate holes, household wood, galvanized pipe, fire hose, plastic, gypsum board and other opening operations. Power Drill Required A hole saw is designed to attach to a POWER DRILL (including pistol drill, bench drill, vertical drill press) and rotate at a high speed. As the saw spins, the teeth cut into the chosen material, removing a circular piece (slug) as it saws through. BENEFITS & ADVANTAGE BI-Metal + High Speed Steel(HSS) Extremely fast sawing with minimal expenditure of force High concentric and side-stroke precision They can cut holes with much larger diameters than traditional drill bits. Because they only cut out the perimeter line of the hole, they are much more EFFICIENT than a spade drill or twist drill. Common Applications Steel, stainless steel, cast iron, copper, bronze, aluminum, wood and plastic. INSTRUCTIONS Pre-drill using light contact pressure. Continue drilling with minimal, even pressure; avoid oscillating while drilling. Follow speed guidelines and use coolant. Allow hole saw to “air” when using with wood and wood alternatives. The saw comes to a complete stop on your material before pulling it away. * Note: Due to manual measurement and production batch is not the same, the size, weight, color will get difference (within 3%) of the normal case. (Please make sure you don't mind before purchasing) This is a premium quality choose for your home improvement!!!

Review: Cuts clean, precise holes—robust and reliable tool - This 150mm bi-metal hole saw has been excellent for my DIY projects and some light professional work. The HSS teeth are sharp and durable; I’ve used it on wood, drywall, and even aluminium with smooth, consistent results every time. The cut edges are clean with minimal need for sanding or touch-ups afterwards. The 30mm cutting depth is more than enough for most domestic jobs, and the hole saw feels solidly built—no flexing or wobble during use. Attaching it to my drill was easy, and it stayed secure even under heavier loads. If you need a reliable large-diameter cutter for extractor fans, ducting, or large pipework, this tool is a great investment. It’s held up well after repeated use, and I’d definitely recommend it to anyone needing a quality hole saw for various materials.

## Features

- ⚙️【FAST & ACCURATE】 The increased hardness of the carbide technology and optimized tooth geometry help our hole saw to provide faster cutting speed and more accurate than standard hole saws cutting everything from wood and plastics to aluminum, steel, cast iron, and stainless steel.
- ⚙️【PREMIUM QUALITY】 The surface layer of bi-metals is typically stronger than an alloy of similar materials as it is made of M42 alloy material, which is featuring high hardness(65-66HRC) to ensure the surface layer durable and rust-proof. The bi-metallic cutting teeth is layered with high speed steel, that increases their hardness and durability, and gives the hole saw excellent cutting ability.
- ⚙️【MORE EFFICIENCY】One of the chief advantages of using a hole saw over a conventional drill bit is the hole saw’s efficiency. Due to the fact that so little of the total amount of material being removed is actually cut, much less power is required, so that you save energy and increase the battery life of your portable power tools.
- ⚙️【VARIETY OF SIZE】 The another advantage of our products is the hole saw’s ability to cut a greater variation of hole sizes. There are a wide range of diameters available on our store from 16mm to 200mm, that can cut with ease when compared with a twist drill or spade drill trying to perform the same task.
- ⚙️【100% Satisfaction】 Provide 60 days free return and replace service to make sure our customers’ satisfaction with every purchase. If you got imperfect Hole Saws, just contact us via email directly, we will be responsible for the quality of our products, just enjoy your purchase.
