The optimal point and clearance angles can be set according to each drilling requirement, which depends upon the drill size and material. You can completely restore worn drills as well as broken drills to a perfect shape.\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eYou create a 4-facet point which gives the ideal cutting performance since the chisel edge gets a point instead of being almost flat as on many drills. A 4-facet point will not walk and the thrust force required is considerably reduced compared to a conventional cone point drill.\u003c\/p\u003e\r\n\u003cp\u003eA precision sharpened 4-facet point generates less heat and the life of the drill is therefore also prolonged. Independent tests show that a Tormek sharpened drill lasts up to 4 times longer than a brand new conventional drill bità ¥?.\u003c\/p\u003e\r\n\u003cp\u003eBy working with the laws of physics and cooling the edge continuously, the risk that the steel becomes overheated and loses its hardness or gets micro cracks is eliminated. You have full control all the time and can see how the sharpening proceeds.\u003c\/p\u003e\r\n\u003ch1\u003eQuestions \u0026amp; Answers\u003c\/h1\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhy is the 4-facet point so beneficial compared to a conventional point?\u003c\/strong\u003e\u003cbr\u003eIt considerably decreases the force required on the core of the drill, i.e the chisel edge, which reduces the heat development and permits an increased force to the cutting edges. It gives the drill a dramatic improvement in cutting performance.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhy does a Tormek sharpened drill last longer?\u003c\/strong\u003e\u003cbr\u003eThe beneficial 4-facet point and the high precision sharpening  °Ãƒâ€ºÃƒ' both cutting edges are sharpened to an exact equal length and symmetrically  °Ãƒâ€ºÃƒ' make the drill work efficiently and the life of the drill bit is considerably prolonged.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat determines an exact and straight hole?\u003c\/strong\u003e\u003cbr\u003eThe 4-facet geometry causes the drill to bore a straight and round hole with very close tolerances. It is crucial that both cutting edges are equal and sharpened to the same angle. This is an essential requirement so that the two edges will work in the same way and ensures that the drill will bore a straight hole, which is not larger than the drill diameter. Otherwise, the longer edge will take most of the cutting force, get overheated and more heavily worn. The result is a drill that will dull rapidly and stop working properly.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat point angle should I have?\u003c\/strong\u003e\u003cbr\u003eDrill bits usually have a point angle of 118 ¡ or 130 ¡. Hardened steel and stainless steel require larger point angles. Also aluminium is best drilled with a larger point angle. When drilling plexiglass, the risk of cracks when the drill goes through the material is reduced with a larger point angle. Centering drills usually have a 90 ¡ point angle.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eIs the clearance angle important?\u003c\/strong\u003e\u003cbr\u003eThe choice of clearance angle is crucial to the cutting performance and duration of the drill. The optimal clearance angle depends both on the drill diameter and the material to be drilled. A harder material requires a drill with a smaller clearance angle while a softer material can have a larger angle. Standard drills have a clearance angle of 11 ¡ and a 118 ¡ point angle which work well for most drilling work.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eHow do you know if the steel has become overheated when using a dry grinder?\u003c\/strong\u003e\u003cbr\u003eOverheating of the steel is often not noticeable, but the consequences are that the drill will dull rapidly and may even break. Unlike conventional drill bit sharpeners, Tormek sharpens with water cooling which is gentle on the steel.\u003c\/p\u003e\r\n\u003ch1\u003eThis is How The Attachment Works\u003c\/h1\u003e\r\n\u003cdiv class=\"block\"\u003e\r\n\u003cdiv class=\"left2\"\u003e\n\u003cbr\u003e\r\n\u003cp class=\"pic\"\u003eThe Primary facets, P and the Secondary facets, S meet in the centre and form a point.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv class=\"right2\"\u003e\n\u003cbr\u003e\r\n\u003cp class=\"pic\"\u003eThe drill is mounted in a Drill Holder (3) on a Guide (2), which in turn runs on a Base (1).\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv class=\"block\"\u003e\r\n\u003cdiv class=\"left2\"\u003e\n\u003cbr\u003e\r\n\u003cp class=\"pic\"\u003eYou start by sharpening the Primary facets.
