Rated 4 out of 5 stars.
If you do any kind of woodworking that involves hinges, dowels, or shelf pins, you know a good forstner bit is a must-have.
This HARFINGTON 40mm (about 1-9/16 inches) bit is a beast.
It's got three carbide cutters and four spurs that work together to give you clean, flat-bottom holes without the tear-out you get from regular twist bits.
The center spur keeps it from wandering, so your holes start exactly where you want them.
The carbide tips are heat-treated for hardness and wear resistance, so this thing stays sharp way longer than standard steel bits.
The spray coating helps resist rust too, which is nice if you work in a humid shop.
The round shank is 10mm (3/8 inch), and the total length is 95mm (about 3-3/4 inches), with a max drilling depth of 65mm (2-9/16 inches).
Solid dimensions for most furniture and joinery work.
The head design is smart—three cutters with a 15-degree angle and an arc curve that helps chips clear out fast.
Less resistance means less strain on your drill and cleaner holes with no burrs.
Works great on softwood, hardwood, plywood, MDF, laminate, and particle board.
Just don't use it on metal or any wood with nails in it—that'll kill the carbide tips fast.
Best used in a drill press or fixed equipment for maximum control, but it'll work in a handheld drill too if you're careful.
Use cutting oil, go slow, and wear safety gear.
This is a pro-level bit that'll make your hinge mortises and dowel holes look factory-clean.
