LAIWEI 160mm hole saw for drilling
Product description
A 160 mm hole saw is a practical choice when you need clean, accurately sized openings for real world installs. This LAIWEI Hole Cutter is made for drilling jobs through common building and workshop materials, using an electric drill for speed and control. With its bimetal style blade and a supplied drill and hex key, it’s set up to get you from tool prep to cutting with less faff, whether you’re working on plumbing, electrics, or general DIY projects 🔧.
The essentials
This LAIWEI hole saw uses a 160 mm cutting diameter, so it’s suited to larger access holes where a standard bit would be too small. The total length is 83 mm, which helps with handling and reach when you’re working on boards and panels. The blade thickness is 1.2 mm, designed to balance rigidity with cutting performance. You also get a centre drill and the hex key needed for setup, so it can be used straight away with compatible drills.
In everyday work, the centre drill matters because it starts the cut with guidance. For drilling through wood and plywood, as well as plastics and thinner metal panels, a guided entry helps you keep the hole where you want it rather than drifting at the start. LAIWEI also builds in a workflow that targets smoother chip removal, so cutting stays more consistent as you go 🔩. Just keep in mind that hole saw drilling should begin from low speed rotation, then proceed with careful alignment.
Key features
The cutting blade is made from high speed steel for durability and sharp performance. According to the manufacturer, the saw blade is HSS high speed steel and is built to be corrosion resistant and wear resistant for longer service life. The centre drill uses high quality 4341 steel, while the tool holder is made of high quality M42 steel, aimed at strong machinability and toughness. These material choices are relevant when you want the tool to keep cutting reliably instead of dulling quickly.
A notable part of the design is the electron beam welding on the high speed steel blade, which the manufacturer links to high cutting performance. The combined pitch is intended to help suppress vibration during drilling, supporting higher precision machining rather than a rough, wobbly cut. The centre drill is described as having springs that push out chips. That chip pushing design can reduce the time and effort spent clearing swarf, while also reducing shock during drilling, helping protect both the insert and the hole as you cut.
It’s a good fit if you are already set up with an electric drill or cordless electric drill and you want a hole saw for common workshop and home improvement tasks. It might not be a great match if you are expecting a plug and play solution for high precision without any drilling rig, because the manufacturer advises using a table drill or an electric drill stand if precision is required.

What’s the best use for it
This hole saw is designed for an electric drill tool and covers a range of materials mentioned by the manufacturer, including gypsum board, plastic, wood, plywood, and thin aluminium panels. It’s also positioned for typical install work such as plumbing and electrical tasks, as well as professional workplace DIY and home improvement jobs. If you’re drilling openings as part of fitting and routing, this kind of size can be especially useful when you need space for components and tidy hole edges.
For smooth results, start with low speed rotation and keep the tool perpendicular to the component. The manufacturer also advises not tilting the drill bit in the centre, since that can affect the shape of the hole and the cut quality. If you are drilling where precision really matters, use a table drill or an electric drill stand. Please also wear protective equipment such as goggles and gloves before you begin, as hole saws can throw off debris during cutting.
The setup includes the hole saw and the centre drill, with 1 hex key for fitting. That means you can mount the tool properly for consistent guidance during the cut, rather than improvising with unsuitable fittings. It suits routine jobs where you want a dependable hole saw for day to day drilling tasks across common construction materials.
