DeSoutter 19710 — Zirconium Nitride Segmented Cast Saw Blade 80mm (5-Pack)
The DeSoutter 19710 is an 80mm Zirconium Nitride (ZrN) coated segmented replacement cast saw blade for the DeSoutter CleanCast CC7 and CC8 systems, sold in a 5-pack. The 80mm format is the largest blade in the CC7/CC8 lineup — purpose-built for adult long leg casts, hip spica casts, and other thick multi-layer applications. The segmented design reduces heat buildup during cutting, while the ZrN coating delivers approximately 50% more hardness than Titanium Nitride for superior blade longevity. A premium, high-value choice for busy orthopedic practices that need maximum performance in their largest blade size.
📏 Why 80mm? Understanding Blade Size Selection
Cast saw blade diameter directly affects how deep a single oscillating pass cuts into the cast material. Choosing the right size reduces procedure time, minimizes patient discomfort, and extends blade life:
| Blade Size |
Typical Use Case |
Best For |
| 32mm |
Pediatric casts; fingers; toes; thin single-layer casts |
Precision work; tight anatomical areas |
| 40mm |
Wrist; forearm; short arm casts; pediatric leg casts |
General upper extremity; moderate thickness |
| 64mm |
Standard adult arm and leg casts; most common clinical use |
Everyday orthopedic cast removal; versatile workhorse size |
| 80mm (This Blade) |
Adult long leg casts; hip spica casts; thick multi-layer casts; high-volume applications |
Faster removal of large, thick casts; fewer passes required |
For practices routinely removing adult long leg or hip spica casts, the 80mm blade significantly reduces procedure time compared to a 64mm blade working through the same cast thickness.
✂️ Segmented Design + 80mm — The High-Volume Combination
On an 80mm blade cutting through a thick, multi-layer cast, the segmented design’s heat-reduction advantage is especially critical. The cut-out sections around the blade circumference reduce total surface contact at any moment:
- ✅ Significantly less heat generated — essential when cutting through thick adult casts where heat buildup is greatest
- ✅ More aggressive cutting action — faster removal with fewer passes on large casts
- ✅ Better chip clearance — cast debris exits through the gaps rather than building up under the blade
- ✅ 5-pack format — keeps your supply stocked for high-volume clinical days without frequent reorders
- ⚠️ The segmented edge can feel slightly more aggressive to the patient — technique and experience matter
🔬 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 as Titanium Nitride, but with a harder, more wear-resistant compound exclusive to the CC7/CC8 platform.
- ✅ ~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
- ✅ Significantly more durable than PTFE — no risk of the coating wearing off after initial use
- ✅ 5-position rotatable mount — rotate to a fresh cutting edge to further extend blade life
- ✅ 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

📊 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 20290 Ion Nitride segmented blade 80mm — 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. The 5-pack format ensures you always have a fresh blade on hand for high-volume clinical days. 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 Zirconium Nitride (ZrN) and Titanium Nitride (TiN) cast saw blades?
Zirconium Nitride (ZrN) is approximately 50% harder than Titanium Nitride (TiN), delivering measurably longer blade life per blade. Both are PVD ceramic coatings and are recommended for plaster and polyester casts. Neither is recommended for fiberglass — for fiberglass, use the Ion Nitride blade (20290).
Can the DeSoutter 19710 cut fiberglass casts?
No. Per DeSoutter guidance, the 19710 ZrN blade is not recommended for fiberglass casts. For fiberglass, use the Ion Nitride blade (part number 20290 for 80mm or 20280 for 64mm), which is the only coating recommended for fiberglass.
Why choose the 80mm blade over the 64mm blade?
The 80mm blade is designed for adult long leg casts, hip spica casts, and thick multi-layer applications where the 64mm blade would require more passes. For standard adult arm and leg casts, the 64mm is the everyday workhorse. The 80mm reduces procedure time on large, thick casts.
What does the 5-position rotatable mount mean?
The 19710 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. This significantly extends the usable life of each blade and maximizes the value of the 5-pack.
What is the difference between segmented and round cast saw blades?
Segmented blades have gaps cut into the blade edge, which reduces heat buildup and improves cutting speed through dense cast materials. Round (full-circle) blades provide a smoother cut and are often preferred for thinner or more delicate casts. The 19710 segmented design is ideal for thick plaster and polyester casts at the 80mm size.
