Carbide Step Drill for Magnetic-Levitation Side-Hole Machines
This step drill is intended for magnetic-levitation side-hole drilling machines, combining tungsten-carbide cutting edges with a high-speed steel shank. A pilot section drills the system hole while the larger stepped diameter opens the cam fitting — one tool, one pass.
Carbide Step Drill for Magnetic-Levitation Side-Hole Machines for Woodworking Production
This step drill is intended for magnetic-levitation side-hole drilling machines, combining tungsten-carbide cutting edges with a high-speed steel shank. A pilot section drills the system hole while the larger stepped diameter opens the cam fitting — one tool, one pass.
Design and Construction
＋The pilot section and larger stepped diameter are ground in one profile: pilot diameters 8–8.5 mm with a 35 mm pilot length, stepping up to a 12 mm step diameter, on 8 or 10 mm shanks, at a 73.3 mm overall length, right-hand rotation. The series is produced in the Sichuan and Dongguan, China manufacturing bases.
How It Works
＋In the side-hole machine the pilot centres the tool in the small system hole while the step enlarges it to the cam diameter at a controlled depth. The carbide edges hold both diameters on MDF and particleboard, keeping the cam seat concentric with the pilot hole.
Applications
- Side-hole drilling on magnetic-levitation side-hole machines
- Cam-fitting and system-hole drilling in cabinet side panels
Suitable Materials
- MDF, density board and particleboard
- Not suitable for plywood / multilayer board or solid pine wood, per the original application list; confirm the material before ordering
Material Comparison: High-Speed Steel (HSS) Tool vs. Solid Carbide Tool
＋Typical industry data for reference. Actual results depend on the workpiece grade, machine condition and feed rate.
| Property | High-Speed Steel (HSS) Tool | Solid Carbide Tool |
|---|---|---|
| Cutting edge hardness | ≈ 60–65 HRC (HSS) | 1,500–2,000 HV (solid carbide) |
| Heat resistance of the edge | Loses hardness above ≈ 315 °C | Retains hardness up to ≈ 1,000 °C |
| Edge life on abrasive panels | Baseline (1×) | 5–10× longer edge life |
| Feed rate at equal quality | Lower | Higher |
| Sharpness retention on MDF / particleboard | Dulls quickly | Holds the edge through long runs |
| Regrinding cycles over tool life | Limited | More regrinds |
| Cut edge quality as the edge wears | More fuzzing and tearout | Consistent clean walls |
| Rigidity in long tools | Lower | Higher (solid carbide body) |
| Typical machines | Light-duty routers and drills | CNC machining centres, multi-spindle borers |
| Cost per hole / metre of cut | Higher over long runs | Lower over long runs |
Delivery Scope
Choose the exact pilot and shank combination from the table and confirm the side-hole machine model.
＋Each order also includes an inspection record. Send the machine model, board material and the pilot/step diameters required so the configuration is confirmed before production.
Why Choose VPOINT
＋VPOINT supports this carbide tool series with:
- One-year warranty on every tool
- Custom diameters, shanks and rotations produced to order
- Regrinding service to extend tool life
- Factory direct since 2008, ISO 9001 certified

Frequently Asked Questions
Which pilot and shank combinations are listed?
＋The chart lists pilot diameters of 8 and 8.5 mm with a 35 mm pilot length, a 12 mm step diameter, 73.3 mm overall length, and shank diameters of 8 or 10 mm, right-hand rotation.
Can it drill plywood or solid pine?
＋No. The original application list covers MDF, density board and particleboard only, and explicitly excludes plywood / multilayer board and solid pine.
Why a stepped profile?
＋The pilot drills the system hole while the step opens the cam fitting in one pass, keeping the two diameters concentric on the side-hole machine.
What should I send for a quotation?
＋The side-hole machine model, board material and thickness, and the required pilot/step diameters and shank size.
