Cottle-Gubisch Chisel Graduated Hollow Cut 18 cm - 7-1/8˝
Buy the Cottle-Gubisch chisel graduated hollow cut direct from the manufacturer. The concave blade face wraps slightly around the bone instead of sitting flat on it, so the hollow cut chisel tracks the curve of the nasal wall rather than skating off it. Both widths are on this page: 5 mm and 12 mm.
Why Surgeons Choose It
- Both widths on one page: 5 mm and 12 mm
- Concave hollow cut face follows the curve of the bone
- Graduated shaft shows cutting depth at a glance
- Bulk discounts on multi-piece orders

Frequently Asked Questions
Which width should I choose?
5 mm for a narrow controlled cut, 12 mm to take a broader section in one pass. The catalog table above lists both with their catalog numbers.
What is a hollow cut blade?
The cutting face is ground concave rather than flat, so it seats on curved bone and is far less likely to slide sideways as you strike.
Is it used with a mallet?
Yes. The flat striking end is made to be tapped with a surgical mallet, and the shaft transmits the force straight down the blade.
Can these be autoclaved?
Yes. They are supplied non-sterile and re-usable, so clean and autoclave them before each use.
Do you sell the full set of widths?
Yes. Order each width from the selector above, or contact us on WhatsApp and we will quote the complete set together with bulk pricing.
Do you supply bulk or OEM orders?
Yes. Contact us on WhatsApp for bulk discounts and OEM or private-label pricing.
