The A190206 set holds 29 different metric sizes of our A100 drills in a plastic storage case opening out for easy access to the drills. The case keeps the drills in size order, with sizes clearly displayed and easy drill selection. The A100 drills in this set can be used for either hand held or machine drilling with a conventional 118 degree split point which provides strength and reduces the cost of regrinding, making the drills very cost effective. With the patented silver ring on the Dormer A100 drill above 6.00 mm, you can be sure this is a genuine Dormer drill. Many different materials can be drilled with the A100, including steels, aluminium and stainless steels and you can be sure you will get a good result every time. The A100 from Dormer has a steam oxide finish to reduce work piece material from sticking to the cutting edge of the drill. Covering all the main metric sizes up to 13.0 mm, the A190206 drill set is an excellent choice. *Note: all drills below 1mm are bright.
