There’s nothing more frustrating on a DIY or trade job than a hole saw that wanders, burns, or dulls after a handful of cuts. The Vearter 3-Piece Bi-Metal Hole Saw Set is built to a different standard — M42 cobalt construction, hex shank stability, and a 20–32mm size range that covers the most common drilling tasks in one ready-to-use kit.
What’s in the Kit?
This is a 3-piece set of bi-metal hole saws in the 20–32mm range, complete with arbors. The key differentiator is the M42 cobalt bi-metal construction — a step above standard HSS (high-speed steel) hole saws. M42 cobalt alloy offers significantly better heat resistance and wear resistance, which means the teeth stay sharp longer and the saw doesn’t overheat and warp during demanding cuts.
The hex shank design provides a secure, slip-free grip in any standard power drill chuck — no wobble, no slippage, just clean, controlled cutting.
Real-World Usage Situations
🔧 Plumbing Installations
Running pipes through walls, floors, or joists requires clean, accurately sized holes. The 20–32mm range covers the most common pipe diameters for domestic plumbing. M42 cobalt cuts through timber, plasterboard, and thin metal without burning or binding — essential when you’re working in tight spaces and need the hole right first time.
⚡ Electrical Work
Installing back boxes, cable conduit, or consumer unit knockouts all require precise circular cuts. The Vearter set’s thin-wall design minimises material removal while maintaining accuracy — critical when you’re cutting into finished walls or working around existing wiring.
🧱 Woodworking & Joinery
Door hardware, lock cylinders, cable grommets, shelf pins — woodworking is full of applications that need a clean circular hole in the 20–32mm range. The bi-metal construction handles hardwoods without the burning that cheaper hole saws produce, and the hex shank keeps the cut true even in dense timber.
🏠 Home DIY Projects
Installing a new door handle? Running cables through a desk? Fitting a bathroom extractor fan? These are exactly the kinds of jobs where having the right hole saw makes the difference between a professional-looking result and a ragged, oversized hole you’re trying to hide. The Vearter set gives the DIYer access to trade-quality tooling at an accessible price.
🔩 The Professional Tradesperson
For electricians, plumbers, and joiners who need a reliable hole saw kit that won’t let them down on site, the M42 cobalt construction is the key. These saws will outlast standard bi-metal sets significantly — fewer replacements, less downtime, more consistent results across a full working day.
Exceptional Value at £42.00
M42 cobalt hole saw sets from premium brands (Starrett, Lenox, Milwaukee) typically retail at £60–£100+ for a comparable 3-piece kit. The Vearter set delivers the same M42 cobalt specification at just £42.00 — a significant saving without compromising on the material quality that actually determines performance and longevity. For both tradespeople and serious DIYers, this is a genuinely smart buy.
