The Oster Pet Clipper Size 30 is a replacement animal clipper blade set that leaves approximately 1/50 inch, or 0.5 mm, of hair. Its short cutting length makes it a choice for grooming work where very little coat should remain. The set includes both the upper and lower blades and is made from carbon steel.

Part number 78913-226 identifies this specific legacy blade set. The replacement listing associates it with Oster animal clipper models 123 and 151. Match that part number and model information to your existing equipment when selecting a replacement.

Use the clipper's installation instructions when changing the blades, and handle the cutting edges carefully. This is a blade replacement for a compatible clipper, with the cutting length determined by the size 30 blade.
