Is #40 the same cut length as #30?

No. #40 is listed at 0.25 mm (1/100 in), while #30 is 0.5 mm (1/50 in). The nominal metric difference is 0.25 mm; neither number guarantees the coat left under every operating condition.

Should I stock #40 as a general body-grooming blade?

Not on the basis of this reference. The supplied #40 uses concern close cutting, including veterinary preparation and foot-pad work. Start with the longer Finish Cut specifications when building a body-grooming assortment.

Does the #40 photograph prove the requested cutter material?

No. The #40 demonstration shows the stainless-steel moving-cutter configuration, not a material certificate. Specify stainless steel, carbon steel or ceramic explicitly, then approve a matching sample and specification before production.

Review the teeth, markings and mounting connection shown here. Cutter material, branding and packaging are specified separately in your quotation and approved sample.

Specify a controlled close-cut application

The supplied reference lists preoperative shaving and foot-pad work for #40. Treat these as professional application contexts, not instructions for home use. Veterinary preparation must be selected and supervised by the responsible veterinary professional.

Referenced breeds: All dog breeds
Referenced body areas: Medical area, Surgical preparation area
Referenced use context: Professional medical and grooming use

Moving blade material options: Carbon steel, Ceramic, Stainless steel
Steel grade options: 3Cr, 4Cr, 5Cr, 420J12, Custom

Compare nearby cut lengths

Compare nominal listed lengths, not a guarantee of the finished coat. Coat condition, preparation and handling affect the result.

Do not describe #40 simply as a shorter #10 replacement in a distributor catalogue. Its 0.25 mm listing is a different purchasing requirement from #10 at 1.5 mm (1/16 in). Ask the buyer whether close cutting is actually required before setting the assortment.

Blade specification	Listed cut length	Published use reference
#40	0.25 mm (1/100 in)	Pre-operative shaving, Foot pads
#30	0.5 mm (1/50 in)	Close trimming, Ears
#15	1.2 mm (3/64 in)	Face, Feet

Confirm the clipper model before ordering

This is an A5 detachable blade, not a universal fit claim. Check the Compatible with model list, then include the exact model and a mounting photo in the RFQ. Blade size identifies cut length; it does not verify the machine.

Check Compatible with model references

Inspection evidence to request

For #40, agree how size marking, tooth edges, cutter alignment and nominated-clipper fit will be checked. Request the lot record and acceptance method instead of inferring close-cut suitability from ISO 9001.

Jizu states an IQC / IPQC / OQC workflow. No size-specific hardness, tolerance, temperature, service-life or batch pass-rate results are published. The checks below are proposed purchase requirements, not measured results.
