How long should a masonry bit last?

Chinese masonry bits normally last for only a couple or three projects, before they get dull. But if that’s all you’re planning to drill, they will be fine. They are very cheap to replace if you ever need more. So it depends on how much drilling you plan to do.

Do masonry drill bits wear out?

It depends on the diameter of your bit and how deep each hole is – I have drilled hundreds of holes with my half inch SDS bit without any sign of weakening (though moderate wear on the tip is apparent).

How do you know if a masonry bit is dull?

After the hole has been started do not attempt to realign an off-center hole by exerting undue side pressure on the carbide tipped drill bits. This may cause the bit to break. If the carbide tipped drill bits aren’t cutting as fast as when new, this is a good indication that carbide-tip is dull.

How do you sharpen masonry bits?

The Grind. A bench grinder provides a high-speed means of sharpening masonry bits. Hold the bit at approximately a 60-degree angle so the bit’s cutting edge is parallel to the grinding wheel. Hold the bit in a sharpening jig and wear heavy work gloves and eye protection.

Will masonry bits drill through concrete?

Drill bits that can drill through concrete are called masonry bits. They are also good for drilling through brick and stone. Drill bits with a tungsten carbide tip are the strongest; when it comes to solid concrete, the sharper the better. Masonry bits cut holes through concrete in two steps.

Can you sharpen a masonry bit?

A bench grinder provides a high-speed means of sharpening masonry bits. Hold the bit at approximately a 60-degree angle so the bit’s cutting edge is parallel to the grinding wheel. Hold the bit in a sharpening jig and wear heavy work gloves and eye protection.

How do you keep masonry bits cool?

The drill bit will get too hot when the drill speed is too high or too much pressure is used when drilling. To keep the drill bit cool reduce the drill speed and/or pressure (push) from the drill operator. Or too slow or too little pressure.

How long will a concrete drill bit last?

How long will bits last? Speed and bit life depend on several factors, including the type of aggregate, age of the concrete, type and sharpness of the bit and the amount of steel or rebar in the concrete. Generally, you can expect to drill between 150 and 250 holes with each bit.
