Best Neiko Step Drill Bits in 2026

【Widely Used】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.

【Material】HSS combined with a titanium coating. More capable and durable.

【Hexagonal Design 】: Hex Shank fits into all power tools more easily and securely, especially for locking into quick change chuck. It is better clamped on the pistol drill to prevent slippage and shedding during the rotation.

[ Use The Drill Bits Longer ] Every Twist Drill Bit has classic High Speed Steel (HSS) construction with a titanium coating that provides ultimate durability and longer drill bit service life through multiple uses without deformation.

[ Drill Precise Holes] The cutting edge of each titanium drilll bit is hardened and honed for sharpness. It also features a chatter-free design with staggered cutting teeth to ensure precise countersinking and clean, smooth holes.

[ Have Every Size You Need ] This universal drill bit set covers sizes: 28 x 3/64", 27 x 5/64", 20 x 1/8", 10 x 5/32", 12 x 3/16", 8 x 15/64", 8 x 9/32", 3 x 5/16", 2 x 23/64", 1 x 1/2", 27 x 1/16", 27 x 3/32", 20 x 9/64", 10 x 11/64", 10 x 7/32", 12 x 1/4", 2 x 19/64", 2 x 21/64", 1 x 3/8".

【High Quality Material】：High-speed steel, also known as HSS, is the most common drill bit for metal applications. It incorporates an element with titanium that makes the drill bit harder than a typical HSS bit and thus suitable for sheet metal working and are ideal for cutting non-ferrous metals, plastic, wood board, etc

【Extra Automatic Center Punch】：You know how when you try to drill into metal or hard surfaces and your drill bit "walks" no matter how much you think it's steady? Yeah, we have a tool for that. The automatic center punch has a heavy-spring action, and you simply place the tip where you want to drill, and it punches a slight indentation in the surface. Just enough so that the drill bit won't walk

【118° Split Point】：These step drill bits have a small point angle of 118° and require less pressure when centering in the material. The point starts drilling at contact, reducing friction, pressure, and heat. The larger the point angle, the higher the contact pressure and the centering in the material requires more pressure

32 Pack Woodworking Chamfer Drilling Tool Set – Nice set of specialized bits useful in creating a nice finished effect for woodworking. Ideal for wood, particle board, fiberboard, logs, plastic boards, PVC pipes used on hand drill, bench drill and electric drill.

7Pcs Countersink Bit for Wood – Made of high carbon steel with high hardness & abrasive resistance, large chip flute and five edge chamfers can drain saw dust faster and easier(Size - 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm). With 1pc hex L-wrench, you could easily remove and adjust counter sleeve depth and drill depth.

8Pcs 3/8" Shank Wood Plug Cutter Drill Bit Set – Made of durable carbon steel, it is used for tapered 1/4", 3/8", 1/2", 5/8" corks to cover recessed screw holes or hide imperfection. Can cut the plug 22mm/23mm/25mm/26mm in depth as well.

1 ) One bit for 11 hole sizes 1/4", 25/64", 35/64", 11/16",13/16", 7/8", 1",1-1/8", 1-7/32", 1-1/4", 1-3/8", so you can drill up holes with different diameters, saving your time and efforts to change bits.

2 ) Genuine M2 high speed steel with the black coating ensures durability and sharpness, reduces the friction, runs cooler, performs well in heat, corrosion and rust resistance, for longer cutting edge life even at extreme temperatures.

3 ) 11 size multiple hole stepped up bits, have many steps which contain multiple diameters, convenient to drill different hole size by using a step drill rather than many drills, ideal for DIY projects at home, garden, workshop etc.

Titanium Nitride coating resists heat and friction, extending the cutting edge life up to 6 times that of other high-speed step drill bits

Made from premium high-speed steel for increased durability

135-degree split-point tip starts drilling immediately with less force and eliminates "walking" across the work surface
