Self-Feed BitĪ self-feed drill bit, similar to the sawtooth, has a threaded end that pulls the bit through the wood swiftly. The teeth cut into the end grain, preventing the bit from skating across the surface. When boring into end grain, sawtooth bits are the preferred choice. Versatile for a variety of purposes, they can cut overlapping holes. Invented for gunsmiths, they create flat-bottomed holes apart from a small indentation. Most commonly found in drill presses and lathes but can also be utilised with hand-held tools. Forstner Bitįorstner drill bits can drill larger diameter holes in timber than other tooling can. This allows you to easily place electrical wires in tight spaces. Electricians use these long, skinny “bell hanger” bits for pulling wires or similar installation work.īesides their long length, they have a hole near the tip for use with pulling wire. Installer drill bits are a specialised tool to install difficult wiring. Suitable for unusually thick applications, they will cut through nails without tool damage. Ship auger bits are a particular type of tool included in this category. It is possible to use with an electric drill, though it will pull through at an alarming rate and no control, better off in a hand brace. They feel more rigid and robust, making them an excellent option for tougher projects. It is 18 inches long, so it can go deep into timber. The auger bit is ideal for drilling through tougher materials. They also offer a more energy-efficient solution. Augers produce cleaner holes than regular woodworking drill bits. The auger drill bit has a threaded tip that can cut a large deep hole. With a clean cutting action for precise dowel holes in wooden workpieces between 3 – 13mm. A (lip and spur) bradpoint centres itself, so you don’t have to worry about drifting. The cutting action is clean and sharp, preventing splintering on the exit hole. Woodworkers know that a brad point drill bit is best for hardwood and softwood. This allows for greater accuracy and stability when drilling. Wood auger bits and Wood drill bits are different names for the same thing for those not in the know.A Brad point bit has a sharp point to position the workpiece with two spurs for cutting. NOTE: And another handy tip: drilling end grain, such as down the center of a post for it’s entire length is not a good use for a auger bit…the feed screw has trouble getting a bite in the pithy center wood…and the pitchy center can load the feed screw and cutter area with sticky wood…nothing to do at that point but remove the auger bit from the hole and get to cleaning all the pitch off the screw threads and cutter. Regular ‘cleaning’ of the hole helps reduce the possibility of this happening. NOTE: Here’s a handy tip: Did you get the long auger bit stuck? It’s best to ‘unstick’ by using a pipe wrench rather than the drill. Wood Auger Bits are for applications such as log homes, timber frames, wooden bridge repairs, arbor work & tree repair, railroad ties, landscape contracting, dock building, bulkheads, remodeling/renovation, piles, manufacturing, and post & beam construction. We stock several types…Irwin, NW, Eliminator, Penetrator, Chasen…in lengths up to 60″” and widths from 1/2″ to 1-1/2″ (depending on the brand).Īuger bits, such as Irwin and particularly NW have a sharp (and sharpenable) cutter that ‘cuts’ the wood as it drills, whereas, if you take a look at a carbide cutter you’ll see it’s more of a ‘rip and push’ (if you can explain it better, let us know, I can’t). Long Woodboring Auger Bits are a specialty of ours.
