Z13D Portable Drill Bit Sharpener – φ3-13mm HSS/Carbide Grinder with 120W Motor
Z13D Portable Drill Bit Sharpener Product Overview
The Z13D is a lightweight, self-contained sharpening station for HSS, cobalt, and carbide drill bits ranging from 3 mm to 13 mm (supports 14 mm max). Unlike bulky bench grinders that overheat and ruin temper, this machine uses a 120W all-copper motor spinning at 4400 RPM to deliver cool, precise grinding. Weighing only 9 kg and occupying 0.02 m³, it fits on any workbench or travels easily to job sites.
Three‑Surface Restoration – Not Just the Tip
Most sharpeners only touch the point angle. The Z13D restores three critical areas:
- Point angle (90°–140° adjustable) – matches original specifications for different materials.
- Front cutting edge (positive rake) – ensures efficient shearing of chips.
- Chip flute (relief angle) – freely adjustable to prevent clogging in deep holes.
Additionally, the center chisel edge is fully adjustable. This feature lets the machine function as a built‑in center drill, eliminating walking and improving centering accuracy – especially valuable when drilling stainless steel or hardened alloys.
Taiwanese Diamond Grinding Wheel – 5µm Precision
The included Taiwan‑made diamond grinding wheel maintains a tolerance of ≤5 microns. It stays sharp for over 3,000 resharpening cycles, allowing you to recoup the machine’s cost in as little as half a month of daily use in a small workshop. Replace a worn wheel only once or twice per year under normal usage.
10‑Second Cycle Keeps Workflow Moving
A typical sharpening operation takes 10 seconds from setup to finish. The tool‑setting mechanism indexes the bit by its original center chisel edge, so even an inexperienced operator achieves correct symmetry on both cutting edges. No need to send bits out for professional sharpening – do it on‑the‑spot and return to drilling immediately.
