Saved me hours of work

As a contractor, I go through these bits quickly. This one lasted longer than expected on a job site with heavy brick and mortar. The center pilot bit keeps it from wandering too.

Perfect for AC Installation

I used this to drill a hole for my new split AC unit. It cut through the reinforced concrete wall like butter. The SDS plus shank fit my hammer drill perfectly. Highly recommend for professionals.

Solid construction

Heavy duty feel. The carbide tips are securely welded. I deducted one star because the extension rod thread was slightly tight, but once loosened up, it worked fine.

Best bit in this price range

I have tried several brands, and this one offers the best balance of speed and longevity. It handled rebar unexpectedly well without losing its edge immediately.

Exactly what I needed

Bought this for a DIY project to run some piping through the garage wall. It was intimidating at first, but the tool made the job straightforward. Clean cuts every time.

Good value but needs water cooling

The bit works well and is sharp out of the box. Just remember to use water to cool it down if you are drilling deep holes, otherwise it smokes a bit. Great price for the quality.

5 FAQ

Q: Is water cooling strictly necessary?

A: While you can drill dry for short durations, we strongly recommend using water cooling for holes deeper than 50mm to prevent overheating and extend the life of the tungsten carbide tips.

Q: Does this come with an extension rod for thick walls?

A: Yes, the package includes a standard extension rod that allows you to drill through walls up to 400mm thick when combined with the main bit.

Q: Will this work on reinforced concrete with rebar?

A: Yes, the tungsten carbide tips are designed to cut through light rebar encountered in residential concrete walls. However, for heavy industrial steel reinforcement, a dedicated diamond core bit is recommended.

Q: Can I use this with a regular handheld drill?

A: No, this bit features an SDS Plus shank designed specifically for rotary hammers and electric hammers. It will not fit or function correctly in a standard chuck drill.

Q: What diameters are available for this model?

A: We offer this core drill in various diameters ranging from 50mm to 150mm. Please select your required size from the dropdown menu before adding to cart.
