Colt Twinland Drill Bits
You’d think manufacturers have done just about everything possible to make drill bits perform better, but it seems they still have a few tricks up their sleeves. Colt, a German drill bit manufacturer, recently introduced some new bits with what almost looks like a four-flute design.
Made of alloy steel, the Twinland brad point bits use a 25º flute with a recessed land — the land is the raised area of the spiral bit. By creating a void in the land, the design removes chips faster and helps prevent one cause of burning, where chips get between the land and the hole wall. The second “land” surface also is supposed to improve guidance and accuracy.
It cuts and scrapes; it peels and notches. It slits and marks; it’s a floor wax and a whipped topping… oops, wrong product. It’s Two Cherries’ new 2Cut. It may look like a chisel, but they claim it’s a universal tool for the craftsman as well a the do-it-yourselfer.
Like its name implies, the 2Cut has two different cutting edges: the 26 mm front edge like a regular chisel and the 90 mm long side edge for cutting use. The remaining side edge can be hit with a mallet. Two Cherries hardens the entire blade in a salt bath to achieve 60±1 RHC and polishes both cutting edges until they’re mirror bright.
