3 PCS HSS Titanium Step Drill Bits Kit 3/16″, 1/2″, 1/4″  Technical Specifications
HSS Step Drill Bit performs smooth drilling in several diameters with one drill bit
Pre-punching is not necessary as the split-point tip allows for an easy start
CNC ground spiral flute enables optimised chip removal and less vibration for even drilling
Highest cutting smoothness due to axial and radial relief grinding
Made of HSS for a long lifetime. Laser-markings for hole diameters.
3-flat shank prevents slipping in the chuck of rotary drills and drivers

High speed steel along with titanium coating ensures outstanding durability andsharpness, can reduces the frictionand drills with lessheat , runs cooler.

Perfect for home DIY, and generalbuilding/ engineering use such as drilling holes in wood,plastic, aluminum, copper,iron sheet and many other types of sheet metal.

Step drills are designed for drilling repetitive holes in steel, stainless steel, copper, brass, aluminium, plastic, plexiglas, laminates and many other thin materials.
Manufactured from premium quality high speed steel with double fluted ground cutting edges for long service life.
No pilot hole required.
Easy to sharpen.
Stepless drilling in the thinnest sheets.
Burr-free drilling without sheet deformation.
Automatic deburring.
Spiral flutes enable easier tool penetration.

For fast, accurate drilling into hard materials like stainless steel, copper, or aluminum without the hassle of changing bits, the 3-piece spiral step drill bit set is the perfect choice. These bits feature a 2-flute design for quicker material removal and cleaner, more precise holes. Made of high-speed steel with a durable titanium coating, they offer long-lasting performance. The 3-flat shank prevents slipping in the chuck, while the new speed point tip ensures smooth, efficient drilling.

1.It is produced by different kinds of materials, such as HSS 4241, HSS 4341, HSS 6542(M2), HSS M35, HSS M42.
2.Different sizes of the Shank: 1/4″ Hex Shank, 7/8″ Hex Shank, Triangle Shank, Round Shank, Square Shank and so on.
3. It is ideal for drilling thin stainless steel plates, aluminum plates,plastic, wood, non-combustible materials, expanding holes, drilling holes, and processing curved surfaces such as pipes.
4.Since the hole is gradually expanded from a small hole to a large hole, drilling of multiple sizes and expansion of the hole are possible.The bite to the tip of the bamboo shoot drill is also finished to feel better than ordinary drills.
5.Step drills two-flute spiral grooved design is deburrs chip, dust and debris for clearance and smooth cutting.
6.118 degree pointed angle with right hand cutting.

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”. 2PC Inch Size 3/16″-7/8″ 1/4″-1-3/8″ High Speed Steel Step Drill Set
3.Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance. 3pce Metric HSS M2 Spiral Flute Step Drill Bit Set
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  4PC 4-12/ 4-20/ 4-32/ 4-39mm HSS Titanium Coated Step Drill Bit Set For Metal
