Description
This six-piece metalworking drill bit set is made from M35 cobalt high-speed steel and is supplied in a twist drill format for general metal drilling and workshop use. M35 cobalt high-speed steel is commonly selected for bits used on harder ferrous materials and for tasks where standard high-speed steel may wear more quickly, subject to correct speed and feed. The six-piece format provides a compact selection for users who need a small set rather than a large indexed case. Typical applications may include drilling metal sheet, mild steel, stainless steel and some cast materials, as well as maintenance, repair and light fabrication work. Users should select the bit diameter that matches the fixing or hole required and should use appropriate clamping and support where necessary. When drilling metal, users should follow the recommended speed and feed for the material and equipment being used, and should consider the use of suitable cutting fluid where appropriate. The set can be kept in a bit holder or tool case and should be checked before use for cleanliness and condition.
