High Speed Drills & Drill Accessories

Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Their suitability comes from their distinctive toughness, resistance to abrasion, their ability to hold a cutting edge, and/or their resistance to deformation at elevated temperatures (red-hardness). High Speed Steel (often abbreviated HSS) is a material usually used in the manufacture of machine tool bits and other cutters. It is often used in power saw blades and drill bits. It is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high speed steel. At room temperature HSS and high carbon steel have an equivalent hardness; only at elevated temperatures does HSS become advantageous.

Diamond Core Drill 1 Inch Diameter

Some Neycraft Core Drilling Instructions:
A 1 inch diamond core drilling agate should be run at approximately 100 R.P.M. To start a hole, begin by kissing the stone with the drill until a clouding appears in the coolant. When this occurs, increase the pressure and continue drilling, Throughout the drilling cycle, oscillate the drill up and down rapidly. To minimize edge chipping when through hole drilling, back the stone with a glass plate.
