Description
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.
🔬 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. 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
- ⚠️ Per DeSoutter’s guidance, not recommended for Fiberglass — for fiberglass-heavy practices, the Ion Nitride blade is the recommended top-tier option
🔵 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 |
📊 CC7/CC8 Cast Saw Blade Coating Comparison — Strongest to Weakest
| 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 | 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 | 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 | 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 | Lower-volume practices; plaster and polyester; budget-conscious clinics |

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).
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.
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.
