8-7/8 in Hole Saw with Arbor - Smooth 8.875 in Cuts

In this review the 8-7/8 in hole saw with arbor is judged as a focused tool for makers, woodworkers and homeowners who need a reliable way to cut an 8.875 in hole, most commonly for cornhole boards and recessed fixtures. The kit delivers a complete set: the large 8-7/8 in bi-metal hole saw, two arbors, extra center bits and an Allen wrench, and it stands out for cutting smooth, relatively low-vibration holes in wood, PVC and drywall. If you want a single tool that makes fast, clean large-diameter holes this review finds it worthy of consideration.

Key Features

• Complete kit: Includes an 8-7/8 in hole saw, two arbors, three center bits and an Allen wrench so you can start cutting right away without sourcing extras.
• Accurate 8.875 in diameter: The cutting diameter is 225 mm (8-7/8 in) which matches common cornhole board specs for a consistent fit.
• Bi-metal construction: HSS carbon steel and bi-metal steel construction with high hardness provides durability for repeated cuts in wood, plastic and thin metals.
• Smooth cutting action: Sharp HSS teeth and a non-binding edge design reduce vibration and leave a cleaner edge on wood and drywall compared with generic hole saws.
• Chip removal ports: Built-in chip removal holes help clear debris quickly so the blade keeps cutting at speed and resists clogging.
• Two arbor sizes: Small and big arbor shanks (10 mm and 11 mm) offer compatibility with different drill chucks and hold-up during heavier cuts.

Who It's For

The hole saw is best for DIYers building cornhole boards, homeowners installing recessed lights and tradespeople cutting large holes in wood, PVC, fiberboard and drywall. Its 8.875 in diameter and 1.2 in blade depth are specifically helpful when a single, consistent large hole is required.

It is less appropriate for heavy structural steel work or very deep holes beyond the 1.2 in blade depth; buyers who need extended depth or specialty metal cutting should look for a deeper or purpose-built metal hole saw designed for thick stock.

Pros & Cons

Pros

• Complete package with two arbors and extra pilot bits so you rarely need additional parts.
• Sharp HSS teeth and bi-metal body provide mostly clean, low-vibration cuts in wood and plastic.
• Chip removal holes speed clearing and maintain cutting performance over multiple holes.
• Accurate 225 mm diameter produces consistent results for cornhole and fixture openings.

Cons

• Cutting performance reports are mixed by users; some find it less razor-sharp out of the box compared with premium brands.
• Blade depth is limited to about 1.2 in, so it is not suitable for deeper work without multiple passes or supplemental tools.

Our Verdict

The 8-7/8 in hole saw kit is a practical, cost-conscious choice for anyone making cornhole boards or cutting large holes in wood, plastic and drywall. It bundles the arbors and pilot bits needed to start right away, cuts with relatively low vibration and produces clean edges for most DIY and light trade tasks. For deeper or heavy-duty metal cutting, consider a deeper or specialized cutter, but for standard board and fixture work this kit offers solid value.
