Dormer Drill Bit, 117mm Total Length, 75mm Chip Flute Length - A002 Series - A0028.5

Take on more metalwork tasks with this jobber drill bit from Dormer. A long chip flute length of 75mm and a drilling depth of 34mm enable you to cut through thick materials. The HSS construction is resistant to impact and wear for effective use on soft metals, including stainless steel, cast iron and copper. Thanks to the modified split point with a 118° angle, the bit is self-centering to cut precise holes.

What's the difference between a jobber and a mechanic bit?

Jobber drill bits have longer flute lengths than mechanic versions, making them a good choice for creating deep holes in soft materials. As mechanic bits come in shorter lengths, they're well-suited to drilling shallow holes in harder materials.
