DIY Network explains the basic types of drill bits used for wood, metal and masonry. These are one of the three main types of wood drill bits, they are characterized by the small point at the tip of the bit. Twist bit – screwdriver bit – masonry – spur point – bullet pilot – countersink – tile – flat wood – hole saw – forstner – wood auger. ‘carbon steel’, these bits are specially ground for drilling wood and should not be used for drilling metals, they tend to be more brittle, less flexible than HSS bits. My steel drilling bits all have HSS on the shank, standing for high speed steel. Bits made for wood should have a slightly longer point on them (narrower tip angle) to allow them to cut their way into the wood rather than to splinter the wood out of it’s path.
Metal drill bits and wood drill bits both come in a variety of sizes that are best used to create a variety of holes. You can find drill bit sets in metric and inch measurement sets. Drill bits are cutting tools used to remove material to create holes, almost always of circular cross-section. General-purpose drill bits can be used in wood, metal, plastic, and most other materials. If used for other materials these tiny bits must be evaluated for equivalent cutting speed vs material resistance to the cut (hardness), as the bit’s rake angle and expected feed per revolution are optimised for high-speed automated use on fiberglass PCB substrate. Someone told me not long ago not to use metal drill bits on wood and vice versa. It does matter – wood drill bits won’t work on metal (destroying the bit in the process, unless used on thin and soft metals) and metal drill bits will increase splintering and tear-out when used on wood (but this depends also on the wood type and the diameter of the bit, and for smaller diameters there is little difference between wood and metal drills bits).
A comprehensive guide to the various drill bit types used in drilling power tools, including simple explanations, tips and photos. Photo of Brad Point (Timber) Drill Bit. However, standard drill bits are generally designed for wood, metal, or masonry, and one can familiarize oneself with different bit types before buying drill bits from a hardware store or an online source like eBay. If you’re drilling through hardened metal, even an HSS bit can wear out quickly, and you may need one made from tungsten carbide or titanium. Wood-boring bits often have a brad point, which allows the user to center the bit and prevents the bit from wandering.
Metal Drill Bits. Wood Drill Bits. Drill Bits
And the better the bit (or arrow, I suppose), the better the result. Carbon steel bits are ground specifically for drilling wood and should not be used to cut metal. Titanium vs. Carbide or Cobalt. I recently used a standard carbon-steel bit to drill thru the steel. Or should I stick with a standard HSS bit for wood? Wood router bits are often easier to use than their metal counterparts, because wood is so much softer than most metal materials. When using wood carving drill bits and other cutting tools, it is not necessary to use cutting fluids, unlike metal. IRWIN 17-Piece Wood, Metal, Masonry Drill Bit Set have the exclusive TURBOMAX tip minimizes walking, delivers 10X faster starts, and stays sharp longer vs. Q: Which is better; cobalt, titanium or black oxide for drill bits? By better I mean will stay sharp longer when drilling wood, metal studs, drywall etc. Whether you are drilling into concrete or masonry, wood, light gauge metal, stainless steel, or just doing some general purpose drilling DEWALT has a drill bit to get the job done.
Drill Bit Types
They can drill into metals, wood, porcelain and even glass, and with a variety of different drill bits available, one can find an appropriate bit for almost. A 4-piece router file set, for wood, iron and non-ferrous metals, contains the following shapes: round, tapered, cylindrical and concave. Bosch – Other accessories for IXO III, IV and V. Brite drill bits are mainly used in wood, metals and plastics. This drill bit is very economical, the 118 point requires you to use a center punch to prevent walking or wandering. Relative Hardness of Drill Bits vs Materials. When a good steel drill bit is used to drill wood, the bit is about 80 times as hard as the wood.
Drilling steel or metal is harder than drilling wood. If you don’t know how to drill steel, you can dull your drill bits quickly. Be sure to use a drill bit designed for steel, such as a cobalt bit. Comparing the cost of framing with steel studs versus wood.
