Double ended drill bits are derivative of HSS-G, fully ground and both ends are drills like double headed bits.
Cutting edge: 135 Deg. split point geometry which ensures no walking and slipping. The total and working lengths are shorter than other HSS drill bits.
Size: Total 21sizes from 2.0mm to 10.0mm including 3.1mm, 3.2mm, 3.3mm which are suitable sizes for drilling holes for rivets.
Depth of hole: 30 percent shorter than HSS-G. Suitable for thin metal sheets because of the length.
Application: While drilling many holes on thin metal sheets, double ended drill bits are preferred because of their short length and long life.
Type of industry: Sheet metal work, automotive body shop and maintenance jobs.
