1.Drill different sized holes: HSS4241 spiral flute step drill bits with hex shank are designed for metal drilling. These drill bits have a step design that allows them to drill different sized holes in one pass, reducing the need for multiple drill bits.
2.Spiral flute advantage: The spiral flute design helps to remove chips and debris from the drilling area, providing a clean and efficient cut. China HSS Titanium Coated Step Drill Bit Drilling Power Tools
3.Material: These step drill bits are made from high-speed steel (HSS) 4241, which is a common material used in drill bits. This material has a high heat resistance, making it suitable for drilling hard materials such as metals.
4. Hex shank: The hex shank design provides a secure grip on the drill bit, preventing slipping and extending the life of the bit. The hex shank also allows for quick and easy changes between drill bits, without needing additional tools. 1/4″-1-3/8″ HSS Spiral Flute Step Drill Bit For Wood Metal

Product Features
1.HSS step drill bits are more expensive than other drill bits, but if you regularly drill through metal, they are a good investment since they tend to last longer.
2.No center punch is needed—the aggressive 135° and 118° Quick-Cut points are self-centering and penetrate quickly with less pressure. Will not “walk” or “wander”. Titanium High Speed Steel Wood Hole Cutter Step Cone Drill Bit
3.Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.
4.Hex-shank drill bits design have a hexagonal shank that provides maximum surface contact with a drill chuck on handheld power tools. This prevents the bits from slipping in the chuck during drilling. Drill bits with a hex shank insert into a standard 3-jaw drill chuck or a drill chuck specifically designed for hex shanks.
5.Perfect Step Drill Bits suitable for drill holes in various material: within 3mm/0.12 inch (Iron Plate, Copper Plate, Aluminum Plate); within 5mm/0.2 inch (Wood, PVC sheet, Insulation Boards).
Not suitable for hard and brittle materials such as stainless steel, glass, tile floors, walls etc
