15 mm works well for fixing Ikea furniture.
I used the 15 mm bit to fix a broken Ikea dresser. The crossbars broke during moving and I wanted to replace the crummy particle board with pine between the drawers. This forester bit worked great for drilling out the holes for the cam locks. I plan on purchasing more sizes later on as I need them (good-bye H.F. bits).

Just remember to use the proper drilling speed on your drill press and to not rush the cut. The Rockler promo video for these bits does a good job showing the capability of these bits.

Just the right size
I drill holes for tea candles in a variety of woods, including white birch and cherry. My 1 1/2" bit fit some of the tea candles but some, including the LED tea candles were slightly over 1 1/2" . The 40 mm bit (1.57") did the trick. Now any tea candle will fit in the hole. Not tight but loose. Just right.

Great drilling bits
These forstner bits are every bit as good as a major brand that I also use. The serated-edge rim of the bit seems to prolong the life and prevents burning. Would purchase again.

Will these bits fit in a JIG IT drill guide? I'm looking for a 20mm Forstner but there's no 20mm long shank bit.

I need a hole that is 1 1/16" for a European hinge what is the closest metric to that size since it is a metric hinge?
A shopper on Jul 22, 2015
BEST ANSWER: European hinges are usually 35mm
You say 30 mm forstner bit "sold separately" from hinges--it is not on the list of metric forstner bits. How do I buy a 30 mm forstner bit?
