6-5/16ft Concrete Hole Saw 160mm Tungsten Core Bit - Durable Drill Kit

In this review of the 6-5/16' (160mm) Tungsten Steel Concrete Hole Saw Kit, the bottom line is simple: it is a practical, heavy-duty option for tradespeople and DIYers who need a reliable core bit for masonry and siding work. The kit stands out for its tungsten steel construction and high-frequency welded joints that offer durability when cutting through stucco, cinderblock, fiber cement siding and backer board. While not flawless, it delivers fast cutting and good value for projects that demand consistent, deep holes for pipes, mini-split lines and exhaust runs.

Key Features

• Tungsten steel construction: Built to resist wear and maintain cutting edge life when used on masonry and hard plank surfaces.
• SDS Plus compatibility: The 220mm SDS Plus shank connects to most major SDS systems for stable, secure mounting and easier tool swapping.
• Triple-edged teeth: Razor-sharp, triple-edged teeth speed through stucco and cinderblock for efficient hole cutting with fewer passes.
• Chip-guiding grooves: Internal and external grooves eject debris during cutting to help keep the hole cleaner and reduce binding.
• Center positioning bits: Two 110mm center drill bits provide precise tracking and stability when starting each hole.
• Water use recommendation: Designed to be used with flowing water on very hard substrates to reduce abrasion and extend bit life.

Who It's For

This kit is aimed at contractors, HVAC installers and serious DIYers who frequently drill through masonry, brick and fiber cement for pipe runs and mini-split installations. Its durable tungsten steel core and SDS Plus shank make it suitable for repeated use on jobs where through-holes must be consistent and clean.

Those who mostly drill thin soft materials or require holes in marble, pebble concrete or rebar-reinforced sections should look elsewhere or use specialized bits, since the manufacturer advises against cutting those materials and high-hardened aggregate can shorten life without proper cooling.

Pros & Cons

Pros

• Durable tungsten steel and high-frequency welding deliver solid build quality for repeated masonry use.
• SDS Plus shank and included center bits give stable starts and broad tool compatibility.
• Triple-edged teeth and chip grooves improve cutting speed and debris ejection for cleaner holes.
• Good value for the build quality compared with many generic core bits.

Cons

• Some users report mixed ease of use if the center bit or shank is not secured properly to the drill.
• Requires water cooling on very hard materials and is not intended for marble, pebbles or rebar.

Specifications

Our Verdict

The 6-5/16' concrete hole saw is a practical choice for installers and serious DIY users who need a tough, SDS-compatible core bit for masonry and siding work. It balances cutting speed, build quality and cost effectively, but users should confirm proper shank seating and use water cooling on very hard substrates to get the best life from the bit.

Frequently Asked Questions

Is this bit compatible with my SDS Plus drill?
Yes, the kit uses a 220mm SDS Plus shank designed to fit SDS Plus tools from major manufacturers.

Can it cut through reinforced concrete?
It is suitable for masonry and block but is not recommended for cutting through rebar; contactors should avoid rebar or use a specialized bit.

Should I use water during cutting?
For high hardness materials use flowing water to reduce abrasion and extend the life of the tungsten core.
