About this item

NEIKO 10185A step drill bit is a versatile tool designed for precise hole-making in steel, wood, and plastic. Crafted from high-speed alloy steel and coated with titanium nitride, it offers durability and longer life. Its cone shape allows for automatic tapping, drilling, and deburring in one step, saving time and effort.

The 12-step size range from 3/16” to 7/8” (4.76mm to 22.23mm) makes it ideal for various projects, whether at home or on the jobsite. The 2-flute spiral design ensures smooth, clean holes with minimal chatter, while the split-point tip prevents walking, ensuring accuracy. Its straight, two-flute design pulls chips out efficiently, reducing heat and extending tool life. Compact and lightweight, it fits easily into toolboxes for on-the-go use. Whether drilling through stainless steel or soft materials, this bit delivers fast, clean results.

Imported from USA, this drill bit is a reliable choice for Indian professionals and DIYers seeking quality tools. It is compatible with standard drill chucks and offers a cost-effective, multifunctional solution for metalworking, woodworking, and plastic projects. Delivery is quick, with all duties included, ensuring a hassle-free purchase experience.

Key Features

  • PREMIUM STEP BIT: Each unibit is constructed of #4241 industrial high-speed steel (HSS) with a titanium nitride coating for durability and strength to punch and drill clean holes in materials like plastic, aluminum, wood, copper, stainless steel, and other types of sheet metal.
  • STEP DRILL BIT FOR METAL: It has a 135-degree split-point tip and features a 2-fluted spiral design that automatically deburrs and expands holes for a cleaner drilling process. With a split point tip that accelerates cutting speed, it prevents walking away from center line of bore, drilling holes in metal is fast, efficient, and clean.
  • STRAIGHT DESIGN: The stepped drill bit with two-flute straight grooved design cuts smooth with minimal chatter, deburrs and pulls chips up and out of the hole effectively.
  • TRI FLANK STEP BIT: The 3/8-inch tri flat shank is ideal for regular drill chucks like 3 jaw drills, cordless drills or drill presses. Tri flat round shanks grip better and run more concentrically for less wobble and cleaner holes.
  • MULTISIZE DRILL BIT: This hole drill bit can drill holes in 12 different sizes from 1/16", 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", and 7/8".
