power tool sourcing blog: guides from the factory floor
Guides, comparisons and import notes from Cirelto — a wholesale power tools supplier in Wenzhou, China. Twenty-eight posts cover wall grinders, concrete leveling and mixing tools and the numbers behind the catalog: specs, silica rules, rpm, MOQ and OEM.
buying guides
one machine class per guide: what the numbers mean and which SKU fits which market
One machine fixes walls that already set; the other levels the pour while it is wet — specs, buyer fit and MOQ 10 terms for stocking both lines.
Five SKUs at MOQ 10 pcs in one mixed LCL shipment — and why the OEM conversation waits for sell-through.
Industry private-label MOQ runs 500–1,000 units — the three-level program that starts at 50 pcs, Pantone matching across 12 SKUs.
CI-G180: 180mm hook & loop pad, 1400W, 2.5 kg for one-hand wall sanding — specs, MOQ and OEM.
Why 150–950 r/min low-speed mixing wins mortar, and which motor class fits your market.
105mm vs 125mm vs 180mm, double-row vs turbo, M14 vs 22.23mm arbor, grit & max RPM.
Cup size & arbor, carbon brushes, dust bags and poles for the CIR-13/16/32/34L series.
280mm vs 380mm discs, steel vs magnesium alloy, and the CIR trowel models each fits.
MOQ by product, 5-7 day samples, T/T & L/C payment, mixed-container consolidation.
comparisons
head-to-head matchups run on the dimensions that decide a purchase
The $20-35 manual wins patch work; ceilings, wall-area days and the 50 µg/m³ silica caps break it — the boundary in one table.
CI-G180 1400W at 2.5 kg against CI-G750 750W at 3.6 kg — and how a first order at MOQ 10 splits across both.
Contact patch, dust capture and overhead balance — and why the installed base of angle grinders is the argument for the category.
The terminology settled: one tool class under two regional names — and the specs that actually decide the buy.
Six dimensions from coverage to dust — and how a wall-finishing assortment should split the two classes.
Same 750W motor, 0.3 kg apart: CI-G750 vs CI-G750B compared for renovation and open-wall work.
knowledge: specs & standards
the engineering behind the catalog, written for buyers rather than engineers
Universal motors ignore frequency — voltage decides. Why a 220V~/50Hz grinder runs normally on Saudi, Philippine and Korean 60Hz mains.
P120 ≈ 116µm vs 120 ≈ 115µm: the wall range coincides, the standards are separate, and polish grades are where they drift.
Six field symptoms and their fixes — filters, hose, over-suction, glazed abrasive and the pre-shift check that prevents most of them.
120, 180, 220: the flattening pass, feathering, and the raking-light check that tells a crew when to stop.
Class M + HEPA for gypsum work, class H when silica enters — the checklist that completes the dust-free system.
Low for plaster and finish, high for coatings and knockdown — what the dial does across the 2026 lines.
The 50 µg/m³ silica caps in the US and EU, what a dust-free wall sander does, and the 4-point sourcing checklist.
M14×2.0: one connection joining mortar mixers and mixing paddles — compatibility matrix and the M10 exception.
Tip-speed math (0.9–8.0 m/s), the 150–950 r/min window mapped to materials, and the paddle-diameter lever.
Which paddle diameter for mortar, plaster and paint, and how to stock all three from MOQ 10 pcs.
regional: import playbooks
order mechanics from MOQ floors to mixed-container freight
230V/50Hz matches the factory standard; HS 8467 runs 5% or 0% under ChAFTA with a Certificate of Origin; the 10% GST is never waived.
The 220V to 120V gap, three ways US buyers close it, the HTS 8467.29 duty stack and a first order at MOQ 10 pcs.
MOQ 10 pcs, OEM from 50, 4 units per carton, mixed-container freight and 30/70 T/T terms.
