Description of π§ Delta Equipment Corp. Pro-17-001
Contains 1 Chisel and Bit Set. Size: 1/4 in. square. Bits made of high-quality steel and resist overheating in heavy use. Designed with a 5/8 in. shank to fit DELTA products; also fits most brands of Mortisers and Drill Press Attachments.
This chisel DOES NOT FIT the POWERMATIC slasher. The shank on the drill is too short. In addition, the appearance of the bit is very rough. It will take a long time to get it smooth, but it can be done. It all depends on how much time you want to spend.
This 1/4" plunge chisel is a perfect design. The "notch" or slot where the chips generated by the drill fall has enough room for the chips to exit. Keeps the bit cooler and therefore cuts cleaner Having tried 3 or 4 other brands this is the keeper.
Most chisel and bit sets in this price range are very similar, but this one has a little more power. I don't know if it's bad because of the smaller chip gap or better because of the stronger ones. It's exactly the same as the one that came with my router bit and I managed to break the one that was grooving white oak when I encountered wild grain, but I think it would with every 1/4-in -Cutter pass. i like price
