The DeSoutter 19640 is a 64mm full round Titanium Nitride coated replacement cast saw blade for the DeSoutter CleanCast CC7 and CC8 systems, sold as a single blade. The gold TiN coating delivers approximately three times the hardness of uncoated stainless steel — providing longer blade life, cooler cutting temperatures, and smoother cast removal for plaster and polyester casts. An excellent everyday workhorse blade for moderate-to-high volume orthopedic practices.
Titanium Nitride (TiN) is a gold-colored ceramic compound applied to the stainless steel blade base using a physical vapor deposition (PVD) process. The result is a surface that is approximately three times harder than uncoated stainless steel, with a dramatically reduced drag coefficient that keeps the blade cutting cleanly through more casts before needing replacement.
What this means in practice:
Clinical context: The CC7 and CC8 are DeSoutter's newest generation cast saw systems, featuring integrated vacuum dust extraction and a redesigned blade mounting system. The 19640 is the TiN round blade designed specifically for these platforms — it is not compatible with the older CC4, CC5, or CC6 systems.
The CC7 and CC8 systems accept both full round blades and segmented blades. Understanding the difference helps you choose the right blade for your clinical workflow:
| Blade Style | How It Cuts | Best For | Available Sizes |
|---|---|---|---|
| Full Round (This Blade) | Continuous circular cutting edge oscillates through the cast material | Standard cast removal; general orthopedic use; plaster and polyester casts | 64mm |
| Segmented | Blade has cut-out segments that reduce contact area — less heat, more aggressive cutting | Fiberglass and harder cast materials; high-volume practices; faster removal times | 32mm, 40mm, 64mm, 80mm |
The 19640 full round blade is the standard choice for plaster and polyester cast removal. If your practice primarily cuts fiberglass or needs faster removal times, explore the segmented blade options in the CC7/CC8 lineup.
The CC7 and CC8 systems introduced a new coating tier — Zirconium Nitride — not available in the older CC4/CC5/CC6 lineup. Understanding the full hierarchy helps you match blade performance to your clinical volume and cast material.
| Rank | Coating Type | How It Works | Best For |
|---|---|---|---|
| #1 | Ion Nitride (Plasma Coated) | Nitrogen ions diffused directly into the steel in a vacuum vessel — near-diamond hardness, no surface coating to wear off; the modification goes into the steel itself | All cast types; maximum durability; high-volume practices; fiberglass and polyester |
| #2 | Zirconium Nitride (ZrN) | Silver-gray PVD ceramic coating; harder and more wear-resistant than Titanium Nitride; excellent thermal stability and corrosion resistance — new to the CC7/CC8 platform | Fiberglass and polyester casts; high-volume practices; superior blade life vs. TiN |
| ⭐ #3 | Titanium Nitride (TiN) ← You are here | Gold PVD ceramic coating; ~3x harder than uncoated stainless steel; reduces drag and keeps teeth sharper longer; excellent for plaster and polyester | Plaster of Paris and polyester casts; moderate-to-high volume practices; not recommended for fiberglass |
| #4 | PTFE (Teflon Coated) | Spray-applied non-stick coating; low friction but tends to wear off after initial use; most economical coated option | Lower-volume practices; plaster and polyester; budget-conscious clinics |
💡 Cutting fiberglass regularly? Consider upgrading to the DeSoutter 19660 Zirconium Nitride round blade — harder than TiN and specifically better suited for fiberglass cast materials on the CC7/CC8 platform.
A patient is always aware of a cast saw near their limb — so a blade that struggles to cut cleanly is a problem on two fronts: it takes longer and generates more heat. Signs it's time to replace your blade:
The Titanium Nitride coating significantly extends blade life compared to PTFE or uncoated stainless steel. Remember to rotate the blade to a fresh position (up to 5 times) before replacing — each rotation gives you a new cutting edge and maximizes the value of every blade.
