![]() ![]() Good drill bits are also worth investing in and should be taken care of and sharpened often as a sharp drill bit cuts better and with much less effort and gives you a much cleaner hole. When starting your DIY journey, I’d recommend at least having a good set of HSS twist bits and some masonry bits, however for more than just your basic holes in the wall, you may want to expand your collection to include the more specialised wood bits as covered above. These bits range in size from 4mm to 16mm and can come in huge lengths of up to 400mm to enable you to drill through walls. You will need to pull out the bit from the material often to prevent dust build up as this can make drilling more difficult and cause overheating. These are best used on a slow rotational speed to prevent overheating and can be used in hammer mode and in gear 1 for tougher jobs. 7 Category Types of reamers Underreamers An underreamer is device designed to run in conjunction with a drill bit. Regular twist bits work fine, but if you are running plumbing or electrical, you should use an auger bit. Sensitive Drilling Machine: This type of drilling machine is used to drill small holes at high speed in lighter jobs or workpieces. In hand-held operation, the workpiece to be drilled is fixed with a vise. Tile drill bitsįeaturing a larger angled tip, masonry drill bits are used to bore into brick, concrete, quarry tiles, stone, and breezeblock. Portable Drilling Machine: This type of drilling machine is often used in workshops to drill small-sized holes. There are also other common types of wood drill bits you may come across for your projects: a countersink with clearance drill bit, a flat wood bit, a plug cutter, a hole saw and a forstner bit. The sizes for this drill bit range from 3 to 10mm. A reamer bit consists of hardened cutting surfaces attached to drill. A REAMER BIT is later used to widen the hole to 15.24 cm (6 in). As a general rule, hard rock roller bits should be used at much slower speeds and higher bit weight than blade bits used for drilling soft formations. They can be used to drill fast through timber of any type as well as plasterboard (and even some plastics) and are mostly used for drilling holes for dowels when a clean parallel hole is required. It is used as an all-purpose bit in every type of formation. They also have a sharp double-bladed thread which helps keep the hole straight and clean when drilling through timber. These have a sharp point on the end to help grip the wood when beginning to drill. Drilling is a cutting process that produces holes by using twist drills, flat drills, or center drills on solid materials to create through-holes or blind holes. The most common you’ll find is a spur point bit, commonly known as a dowel bit. Various cutting processes of drilling, reaming, or counterboring are done using different types of drill bits. It’s not often you’d need a wood drill bit for walls, as you can drive screws straight into wooden studs for a superior hold, but when working with plasterboard or working with timber on other building projects, you’ll come across a few different types of wood bits to get the job done right. ![]()
