Precision Multi-Step Drilling

Step drill bits deliver high-performance drilling action with 5 to 13 incremental step sizes, ranging from 4mm to 32mm in diameter. Each step has a 2mm increase, allowing for smooth, accurate enlargement of holes and the added benefit of deburring edges as you work. With cutting accuracy to 0.1mm, these bits are ideal for projects requiring different hole diameters and clean finishes.

Durable Titanium Nitride Coating

A polished TiN (Titanium Nitride) coating enhances surface hardness and wear resistance, offering increased lifespan and reliability under frequent use. The fully heat-treated HSS construction ensures hardness levels of HRC 60-65, making these bits suitable for tough materials like steel plate and aluminum, while also reducing tool replacement frequency.

Efficient Chip Removal and User Safety

The spiral flute design efficiently evacuates chips from the cutting zone, maintaining drilling speed and preventing bit clogging. Non-slip shank types (straight or 3-flat) provide secure clamping in drill chucks, minimizing slippage and enhancing operator safety during manual or power-operated drilling.

FAQ's of Step Drills:

Q: How do step drill bits improve drilling efficiency in sheet metal and other materials?

A: Step drill bits feature a spiral flute and multi-step design that allows you to drill and enlarge holes in one continuous operation. This reduces the number of tool changes needed and provides consistent chip evacuation, improving speed and accuracy when working with sheet metal, plastics, aluminum, wood, PVC, and steel plate.

Q: What advantages does the titanium nitride coating offer for step drill bits?

A: The TiN (Titanium Nitride) coating increases surface hardness and reduces friction, which prolongs bit life and maintains cutting performance. It also enhances wear resistance, making the bits ideal for frequent use and for processing tougher materials without excessive wear.

Q: When should I choose a step drill bit with a 3-flat shank over a straight shank?

A: A 3-flat shank provides better anti-slip performance in the drill chuck, making it suitable for heavy-duty applications and power tools where higher torque is involved. Straight shanks are appropriate for general drilling where slippage is less of a concern.

Q: Where can step drill bits be used, and which machines are compatible?

A: Step drill bits are suitable for use with drill presses, electric drills, and cordless drills. They accommodate various chuck sizes-1/4, 3/8, and 1/2 inch-allowing flexibility in both industrial and home workshop environments for drilling through multiple materials.

Q: What is the benefit of spiral flute design in these step drill bits?

A: The spiral flute improves chip evacuation during drilling, preventing clogging, maintaining a cleaner hole, reducing friction, and helping to keep drilling temperatures lower. This results in smoother operation and longer bit life.

Q: How does the deburring function of step drill bits simplify the drilling process?

A: As you drill and enlarge holes, the conical multi-step structure automatically deburrs the edges, eliminating the need for a separate deburring tool. This streamlines your workflow and produces cleaner, finished holes faster.

Q: What is the typical cutting speed and torque capacity of these step drill bits?

A: Step drill bits operate at cutting speeds of 20-40 m/min, depending on the material, and handle maximum torque up to 50 Nm. This ensures efficient drilling and step enlarging while maintaining optimal accuracy and durability.
