## Description

Product Description SS SHOVAN 4-Flute Step Drill Bit Sets Prevent drill from burn Slow down the speed before using the drill, the larger the diameter of the hole, the slower the speed, speed ≤ 800r/min. Suitable cutting fluid (water, oil, or other lubricants and coolants, depending on the material of drilling) to cool while working, it can effectively extend the service life of the drill bit, especially in the case of continuous drilling. If each step exceeds 20 seconds, please check the method. If there is slippage and no swarf, please check the speed. 15 Step Bit: 4-32mm (4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, 32mm) 9 Step Bit: 4-20mm (4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm) 5 Step Bit: 4-12mm (4mm, 6mm, 8mm, 10mm, 12mm) Hex Shank: 1/4'' (6.35mm) Improved sharpness & accuracy for smoother cuts. Edges prevent metal filings flying around. Outstanding heat dissipation for longer use life. Optimized cutting edges make transitions between between the individual steps smoother.

Review: Recommend for professional and DIY - For the price these are possibly unbeatable. I use these for professional electrical installation work. I only use for thin plastic and unhardend metal materials. Very versatile. They make a lot of holes in metal before blunting for the price point. They are cheap and can take some abuse if you needed to drill something you wouldn't want to blunt expensive cutters on. If you loose then no problem either. Thats why these are my go to atm. Buying expensive is sometimes a waste of money. If you are drilling metal sheet or softer than hardned metal materials these are excellent.
Review: A good choice and price. - These were all very good. Strong and so far reliable. I would recommend these bits and buy them again in the future.
