HSS stands for High Speed Steel. HSS drill bits are also commonly called twist drills or jobber drill bits.
They are used to drill various materials including wood, metal and plastics.
Our Presto brand of HSS drills is available in most sizes coated in TiN, an acronym for Titanium Nitride, which is a very hard and durable ceramic material.
For hole sizes greater than 13mm we stock HSS Blacksmith drills, by Addax. These versatile drill bits have a shank that is reduced to 12.5mm, enabling them to be used in drills with a standard 13mm or ½” chuck.
The most common thread type in production today. Usually specified as M then a number x another number. This signifies the thread diameter and the length of the fastener.
For example, M4 x 30 means that the major thread diameter (the external distance across the outside of the thread) is 4mm and the length is 30mm. Length is usually measured from the underside of the fastener head.
