How to put a circle cutter on a drill?
For hole saws or circle cutters, attach them to the drill using the appropriate arbor/mandrel, ensuring it’s tightened securely before use.
How to tell a drill bit is for wood?
It has a sharp center point and often spurs on the edges.
How to tell if a drill bit has a carbide tip?
Look for a silver or gray insert at the cutting edge—different from the bit’s main body.
How to tell if a drill bit is carbide tipped?
The cutting edges will be visibly brazed onto the steel body, often a different color or texture.
How to tell if a hole saw is for metal or wood?
Metal hole saws have fine, hardened teeth or carbide tips; wood hole saws have larger, aggressive teeth. Check the packaging or markings.
How to tell the difference between a wood drill bit and a steel drill bit?
Wood bits have a point and spurs; steel bits are blunter with a chisel edge for cutting metal.
How to use a hole saw with a hole already?
Clamp a scrap board over the existing hole, drill through the board to keep the saw steady as it enters.
Is a flat wood bit better than a hole saw?
Flat (spade) bits are faster and cheaper; hole saws cut cleaner and handle larger diameters better.
Is a hammer drill better for masonry?
Yes — hammer action chips the material as you drill, making the process faster and easier on the bit.
Is an annular cutter only made for through holes?
Mostly, yes—they’re optimized for through holes, but with careful depth control, they can be used for blind holes.
