Portable Drill Bit Sharpener φ3–13mm | 120W 4400RPM Tool Grinder for HSS & Carbide Bits
Product Overview
Keeping drill bits in peak condition is essential for precision drilling and material efficiency. This portable drill bit sharpening machine (model Z13/Z13D) restores worn HSS and carbide bits from 3 mm up to 13 mm in diameter (supports 14 mm max). With a 120W all-copper motor running at 4400 RPM, it delivers consistent grinding power without overheating – ideal for small workshops, on-site maintenance, and DIY garages.
Unlike bulky industrial sharpeners, this unit weighs just 9 kg and occupies only 0.02 cubic meters. You can move it between workbenches or carry it to job sites effortlessly. The Taiwan-made diamond grinding wheel achieves 5‑micron precision, sharpening not only the point angle but also the front cutting edge, chip flute, and center chisel edge.
Why This Grinder Stands Out
Grinding range: φ3 – φ13 mm (φ14 optional) – covers the most frequently used drill sizes.
Point angle adjustable from 90° to 140° – suitable for different materials (soft metals, steel, cast iron).
Adjustable center chisel edge – eliminates the need for a separate center drill, improves centering and chip evacuation.
10‑second sharpening cycle – one worn bit is restored in less time than it takes to find a replacement.
3000+ grinds per grinding wheel – the Taiwanese diamond wheel maintains high hardness and sharpness, delivering a return on investment within half a month of regular use.
All‑copper motor – runs cooler and more efficiently than aluminum-wound motors, with longer service life.

What You Can Sharpen
Standard twist drills (HSS / cobalt / carbide)
Step drills (within diameter range)
Masonry bits (carbide-tipped) – with proper wheel care
Damaged chisel edges – fully restorable thanks to the adjustable center point
The machine also allows you to customize the relief angle (back angle) for better chip flow, reducing clogging when drilling deep holes.
Built for Real Workshop Conditions
The housing uses powder coating certified under EU EPD standards – it resists scratches, oil, and solvent spills, keeping the machine professional-looking after months of use. The tool‑setting mechanism aligns the bit according to its original center chisel edge, so even an inexperienced operator can achieve factory-grade geometry.
For business buyers, this model is an excellent entry‑level resharpeners for tool rental shops, hardware stores offering sharpening services, or manufacturing lines that need a quick on‑floor solution.
