The DeSoutter 19730 is a 64mm Zirconium Nitride (ZrN) coated segmented replacement cast saw blade for the DeSoutter CleanCast CC7 and CC8 systems, sold in a 5-pack. Combining the heat-reducing advantages of a segmented blade geometry with the ultra-hard ZrN coating — approximately 50% harder than Titanium Nitride — the 19730 delivers faster cast removal, lower heat generation, and significantly longer blade life than TiN or PTFE options. An outstanding choice for high-volume practices that demand consistent performance across a large number of casts.
The segmented blade design features cut-out sections around the blade circumference that reduce the total surface area in contact with the cast at any moment. On a high-volume clinical day, this difference is felt immediately:
The combination advantage: When you pair segmented geometry with ZrN's 50% hardness advantage over TiN, you get a blade that cuts faster, runs cooler, and lasts longer — all in a 5-pack format that keeps your supply stocked without constant reorders.
Zirconium Nitride (ZrN) is a silver-gray PVD ceramic coating applied to the stainless steel blade base using the same physical vapor deposition process as Titanium Nitride — but with a harder, more wear-resistant compound that is exclusive to the CC7/CC8 platform.
| Blade Style | How It Cuts | Best For | Available Sizes (ZrN) |
|---|---|---|---|
| Full Round | Continuous circular cutting edge oscillates through the cast material | Standard cast removal; plaster and polyester; general orthopedic use | 64mm |
| Segmented (This Blade) | Cut-out segments reduce contact area — less heat, more aggressive cutting, better chip clearance | High-volume practices; faster removal; heat-sensitive patients; polyester and plaster | 64mm, 80mm |

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 teeth 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 20280 Ion Nitride segmented blade 64mm — nitrogen diffused directly into the steel for near-diamond hardness with no surface coating to wear off.
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 Zirconium Nitride coating delivers meaningfully longer blade life than TiN or PTFE. The 5-pack format ensures you always have a fresh blade on hand. Remember to rotate to a fresh position (up to 5 times) before replacing to maximize every blade's value.
