Cobalt HSS steel stainless steel drill bit set, 10 pieces, GTNSDS-10, 1 set

X-shape thinning (3mm or more) provides good bite during cutting, enables quick drilling with less force, and improves work efficiency. Suitable for drilling holes in stainless steel. Hexagonal shaft: 6.35 mm Set includes: 1.5, 2.0, 2.5, 3.0, 3.2, 3.5, 4.0, 4.5, 5.0, 6.0mm Shape: X-shape thinning (3.0mm or more) Note Before use, check the contents of the set to make sure there are no abnormalities such as deformation or cracks. Do not wear gloves such as work gloves as they may get caught in the rotating parts. When using a drill bit with an impact driver, be sure to avoid subjecting the shank to impact as there is a risk of damage to the drill bit. Do not use drill bits for any other purpose or on heat-treated steel. Also, do not use it on thin, brittle materials such as acrylic or polystyrene resin. When cutting thick wood, chips may get into the grooves of the drill bit, making cutting difficult. Please be careful, especially with drill bits up to 3mm, as they are prone to breaking if pressed too hard.
