#3F Dog Clipper Blade (13 mm)

Thick, heavy coats meet their match in the VUNRO #3F dog clipper blade, a 13mm high carbon hardened stainless steel blade built for body sculpting and confident coat work. Its longer teeth glide through dense fur like a comb, reducing the need for scissoring on larger jobs.

• 13mm cutting length ideal for shaping thick and heavy coats with fewer passes
• Longer teeth comb the coat as you clip, leaving a plush finish that stays easy to manage between grooms
• High carbon hardened stainless steel holds a sharp edge session after session
• Cuts down scissoring time on body sculpting and full body work

This blade is compatible with Andis, Oster, Heiniger and most other brands of A5 pet hair clippers. Add the VUNRO #3F to your grooming toolkit and feel the difference on every long coat.

A little preparation makes clipping smoother and helps your blade do its best work.

1. Start with a clean, dry coat. Brush out loose hair and gently comb through tangles first. Do not force a blade through tight mats; ask a professional groomer for help if the coat is matted close to the skin.
2. Choose the finish before you start. This 3F blade leaves approximately 13 mm. Coat texture, preparation and clipping direction affect the finished look. If you are unsure, start with a longer length and test a small area.
3. Let the blade glide. Use light pressure and smooth, overlapping passes with the flat of the blade against the coat. Stop if it drags or pulls instead of pushing harder.
4. Keep checking comfort. Check blade temperature frequently and pause or change to a cool blade when needed. Give the dog a break if they become restless or uncomfortable.

1. Clear away hair and debris. Switch the clipper off before removing the blade or brushing it clean. Clean both the teeth and the back of the blade with a soft blade brush.
2. Oil regularly. Use clipper-blade oil at the contact points, following the clipper and oil instructions. Wipe away excess before clipping. Cooling spray is not a substitute for proper oiling.
3. Watch the temperature. Every blade can warm up in use. Check it regularly and allow it to cool, or swap to a spare, before continuing.
4. Clean after each groom. Use a suitable blade cleaner or disinfectant as directed, including its contact time. Remove residue, dry thoroughly and re-oil before storing.
5. Protect the teeth in storage. Keep the blade dry and protected from knocks. Do not use a blade with chipped or damaged teeth.

If a clean, oiled blade still pulls, stop and check that it is fitted correctly. The cutter or your clipper's blade drive may need attention. Contact us for help choosing the right replacement instead of guessing.

Will this blade fit my clipper?

It fits a compatible detachable A5 clipper. A5 blades do not fit VUNRO D-Series clippers or the FlexFit PRO, MaxFit PRO and PawTrim blade systems. Check your model in our blade compatibility guide, or send us the model name if you are unsure.

How much coat does this blade leave?

The 3F is rated at 13 mm. That is a guide to the finish, not a promise that every coat will look identical. Clipping against the coat's growth generally gives a closer result than clipping with it.

Can I use a guard comb over it?

Only use a guard comb with a blade number and width approved for that set. Not every A5 blade is suitable underneath a guard comb; check the set's compatibility before ordering.

Why is my blade pulling or leaving lines?

Check for tangles, trapped hair, a dry blade or an incorrect fit first. Clean and oil it, check the temperature, and use light, even passes. If the problem continues, stop and ask us for advice; pressing harder can make it worse.

Can I replace the cutter without replacing the whole blade?

Replacement cutters are available for A5 blades. Match the cutter to the blade's size, width and type: standard, wide and skip-tooth cutters are not all interchangeable. Ask us to check the match if you need a hand.
