About this item

  • 🔥 The step drill bit is made from upgraded high speed steel characterized by well-balanced toughness, wear resistance and red hardness properties for better and faster hole -drilling performance. The cobalt coating makes the drill bit more durable so that it can last for years with uncompromised quality.
  • 🔥 The spiral dual-flute design prevents metal fillings from flying around and clears chips faster thus it can drill more smoothly without heating up.
  • 🔥 The rapid strike tip drills twice as fast as the average step drills and can drill acrylic, PVC, wood, aluminum and iron sheets up to 0.2’’ in thickness.
  • 🔥 CORTOOL drill bit is bigger in size so it can drill holes with larger dimensions.
  • 🔥 10 hole sizes: 1/4; 3/8; 19/32; 3/4; 1'; 1'3/16; 1'3/8; 1'5/8; 1'3/4; 2'.

This has got a huge cutting diameter and appears to be very durable, I have only used it once, but it cut a 1' 5/8" hole in sheet metal. Make sure you have a good hold of your drill, this big of hole can be difficult to cut with a hand held drill motor.

At the price paid, this is a ridiculous deal.I've already used several bits multiple time and had absolutely no problem with them on steel (light gauge), aluminum, plastic and wood.Not sure about longevity, but I may never find that out. If you need a comprehensive kit for semi-serious work, this is a good deal.
