DeSoutter 19660 — Zirconium Nitride Full Round Cast Saw Blade 64mm (5-Pack)
The DeSoutter 19660 is a 64mm full round Zirconium Nitride (ZrN) coated replacement cast saw blade for the DeSoutter CleanCast CC7 and CC8 systems, sold in a 5-pack. Zirconium Nitride is an ultra-hard PVD ceramic coating that is approximately 50% harder than Titanium Nitride — delivering superior blade longevity, reduced heat generation, and consistently smooth cutting performance across more casts before replacement. An excellent high-value choice for moderate-to-high volume practices that want premium blade life in a cost-effective multi-pack format.
🔬 Zirconium Nitride Coating — What You Need to Know
Zirconium Nitride (ZrN) is a silver-gray PVD ceramic coating applied to the stainless steel blade base — the same physical vapor deposition process used for Titanium Nitride, but with a harder, more wear-resistant compound. ZrN is exclusive to the CC7/CC8 platform and represents a meaningful step up from TiN in terms of raw coating durability.
- ✅ ~50% harder than Titanium Nitride — measurably longer blade life per blade
- ✅ Excellent thermal stability — maintains cutting performance even as blade temperature rises during use
- ✅ Superior corrosion resistance — silver-gray ZrN layer protects the steel base in clinical environments
- ✅ 5-position rotatable mount — rotate to a fresh cutting edge to further extend blade life
- ✅ 5-pack format — ideal for stocking a supply without frequent reorders
- ✅ Excellent performance on Plaster of Paris (Gypsona) and Polyester casts (Deltalite/Benicast/CellaCast)
- ⚠️ Per DeSoutter’s guidance, not recommended for Fiberglass (Deltalite/Scotchcast) — for fiberglass-heavy practices, the Ion Nitride blade is the recommended top-tier option
Clinical context: The CC7 and CC8 are DeSoutter’s newest generation cast saw systems. The 19660 ZrN round blade is exclusive to these platforms — it is not compatible with the older CC4, CC5, or CC6 systems.
🔵 Round vs. Segmented Blades — Which Do You Need?
| 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; plaster and polyester; general orthopedic use |
64mm |
| Segmented |
Cut-out segments reduce contact area — less heat, more aggressive cutting, better chip clearance |
Fiberglass and harder cast materials; high-volume practices; faster removal times |
64mm, 80mm |
Need a ZrN segmented blade? See the DeSoutter 19730 ZrN Segmented 64mm or the DeSoutter 19710 ZrN Segmented 80mm.
📊 CC7/CC8 Cast Saw Blade Coating Comparison — Strongest to Weakest
The CC7 and CC8 systems introduced Zirconium Nitride — a coating tier 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 including fiberglass; maximum durability; highest-volume practices |
| ⭐ #2 |
Zirconium Nitride (ZrN) ← You are here |
Silver-gray PVD ceramic coating; ~50% harder than Titanium Nitride; excellent thermal stability and corrosion resistance — exclusive to the CC7/CC8 platform |
Plaster and polyester casts; high-volume practices; superior blade life vs. TiN; 5-pack value |
| #3 |
Titanium Nitride (TiN) |
Gold PVD ceramic coating; ~3x harder than uncoated stainless steel; reduces drag and keeps edges sharper longer |
Plaster of Paris and polyester casts; moderate-to-high volume practices |
| #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 |
💡 Need the absolute maximum blade life? Consider upgrading to the DeSoutter 20240 Ion Nitride round blade — nitrogen diffused directly into the steel for near-diamond hardness with no surface coating to wear off.

⏱️ When Should You Replace Your Cast Saw Blade?
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 blade requires more passes or pressure to cut through the cast
- Increased heat felt through the cast padding during removal
- Longer cast removal times than usual
- Visible wear or dullness on the cutting edge
The Zirconium Nitride coating delivers meaningfully longer blade life than TiN or PTFE — and the 5-pack format ensures you always have a fresh blade on hand without frequent reorders. Remember to rotate to a fresh position (up to 5 times) before replacing to maximize every blade’s value.
Frequently Asked Questions
What is the difference between the DeSoutter 19660 ZrN round blade and the 19640 TiN round blade?
Both are 64mm full round blades for the CC7/CC8. The 19660 has a Zirconium Nitride (ZrN) coating that is approximately 50% harder than the Titanium Nitride (TiN) coating on the 19640, delivering measurably longer blade life per blade. The 19660 also comes in a 5-pack for better value at high volume. Both are recommended for plaster and polyester casts only.
Can the DeSoutter 19660 cut fiberglass casts?
No. Per DeSoutter guidance, the 19660 ZrN blade is not recommended for fiberglass casts. For fiberglass, use the Ion Nitride blade (part number 20280 for 64mm segmented or 20240 for 64mm round), which is the only DeSoutter coating recommended for fiberglass.
What is the difference between Zirconium Nitride (ZrN) and Titanium Nitride (TiN) coatings?
Zirconium Nitride (ZrN) is approximately 50% harder than Titanium Nitride (TiN), delivering measurably longer blade life per blade. Both are PVD ceramic coatings recommended for plaster and polyester casts. ZrN is exclusive to the CC7/CC8 platform and represents a meaningful step up in coating durability.
What does the 5-position rotatable mount mean?
The 19660 blade features a 5-position rotatable mount, meaning you can rotate the blade to a fresh cutting edge up to 5 times before replacing it. Combined with the 5-pack format, this gives high-volume practices maximum value per order.
Is the DeSoutter 19660 compatible with the CC4, CC5, or CC6 cast saws?
No. The 19660 is designed exclusively for the DeSoutter CC7 CleanCast and CC8 systems, which use a different blade mounting system than the older CC4, CC5, and CC6 saws. For CC4/CC5/CC6 blades, see our dedicated CC4/CC5/CC6 blade collection.
