Fansipro M35 - M35 cobalt high speed steel 1 4-20 MM

Details: *Made of high quality material, durable and practical to use *M35 cobalt high speed steel drill bits 4-12 / 4-20 / 4-32mm spiral groove triangular drill for stainless steel *Mainly used for drilling thin steel sheets within 3mm. One drill bit can be used instead of multiple drills. It can process different diameter holes according to needs, and can realize large-hole one-time processing without changing drill bits and positioning holes *Used in automotive processing, aerospace, sheet metal processing, electrical installation and maintenance industries, and easy to carry products to meet the needs of high-altitude work with hand drills and other tools *Cutting capacity: If the hand drill is used, the power needs to be 550W, the thickness of the iron plate is ≤5mm, the thickness of the ordinary steel plate is ≤3mm, and the thickness of the stainless steel plate is ≤1mm *If it is used for bench drill, the thickness of iron plate is ≤5mm, the thickness of ordinary steel plate is ≤5mm, and the thickness of stainless steel plate is ≤2mm *Material: High speed steel *Color: As Pictures Show *Optional Type: 4-12mm / 4-20mm / 4-32mm/ 4-12mm+4-20mm+4-32mm Note: 1.Continuous cooling is required during operation to protect the drill bit from burning at high temperatures due to cutting friction. 2.Drill maintenance: The drill bit has been used for a long time, and the head can be polished. Apply anti-rust oil after each use to prevent rust. Optioanl Package Contents: Package 1#: 1*Drill Bit Package 2#: 3*Drill Bits
