Review

I’ve tried a lot of drill bits in my nearly six decades as a woodworker, with varying degrees of success. These German-made, high-speed-steel Colt drill bits are the finest I’ve used.
For example, I used a 1-1 ⁄2" MaxiCut Forstner bit to bore 100 holes 1/2" deep in hard maple, and the bit not only cut clean, accurate holes, but it also stayed cooler than other Forstner bits put to the same test. I like the way the unique, stepped teeth on the chip-breakers slice off narrow shavings that don’t clog up my shop vacuum the way the large spiral shavings from other Forstner bits tend to do. Each of the MaxiCut Forstner bits features two shallow flats on its shank, and because of that I couldn’t make them slip in a drill chuck no matter how hard I tried. These flats work with the RotaStop 5" Morse-taper adapter and 8" extension to bore deep holes using your drill press or lathe. I used this setup with a 35mm bit to bore the 10" length of a 38mm-square hard maple blank. It never wavered side-to- side nor burned the wood. Impressive. I found Colt’s Five Star brad-point bits and steep-fluted PenBlank pen- drilling bits to be exceptional. Both bored clean, precise holes without tear-out in all materials and cleared chips without having to repeatedly back the bits out of the wood. The brad-point bits sell individually and in Imperial and metric sets of seven. The pen bits come individually and in 5-packs. The MaxiCut Forstner bits come in 20 Imperial sizes and 24 metric, individually or in sets of five and 10. —Tested by Dean Fiene
