DeSoutter 19670 — PTFE Coated Segmented Cast Saw Blade 32mm (5-Pack)
The DeSoutter 19670 is a 32mm PTFE coated segmented replacement cast saw blade for the DeSoutter CleanCast CC7 and CC8 systems, sold in a 5-pack. The 32mm diameter is the smallest blade in the CC7/CC8 lineup — purpose-built for precision work in tight anatomical areas: pediatric casts, finger and toe casts, and thin single-layer applications where a larger blade would be impractical or unsafe. The segmented design reduces heat buildup, while the PTFE coating provides a low-friction cutting surface that runs cool on plaster and polyester casts while the coating remains intact.
📏 Why 32mm? The Precision Blade for Small Casts
The 32mm blade is a specialist tool — not a general-purpose workhorse. Its small diameter gives the clinician precise control in areas where a 64mm or 80mm blade would be too large to maneuver safely:
| Blade Size | Typical Use Case | Best For |
|---|---|---|
| 32mm (This Blade) | Pediatric casts; finger and toe casts; thin single-layer casts; tight anatomical areas | Precision work where a larger blade cannot safely maneuver |
| 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 | Adult long leg casts; hip spica casts; thick multi-layer casts | Faster removal of large, thick casts; fewer passes required |
Many orthopedic practices keep a supply of 32mm blades specifically for pediatric patients and digit casts — situations where patient safety and precision matter more than cutting speed.
✂️ Segmented Design — Less Heat in Tight Spaces
The segmented blade design features cut-out sections around the blade circumference that reduce total surface contact with the cast. On a small 32mm blade used in tight anatomical areas, this heat-reduction advantage is especially valuable:
- ✅ Less heat generated — critical when working close to small pediatric limbs or digits
- ✅ More precise cutting action — segmented geometry helps navigate tight spaces with less drag
- ✅ Better chip clearance — cast debris exits through the gaps rather than building up under the blade
- ⚠️ The segmented edge can feel slightly more aggressive to the patient — technique and a calm approach matter especially with pediatric patients
🔬 PTFE Coating — What You Need to Know
PTFE — commonly known as Teflon — is a non-stick, low-friction coating applied to the stainless steel blade base. When intact, it creates a smooth, lubricious surface that slides through casting materials with less drag and less heat than an uncoated blade:
- ✅ Low-friction non-stick surface — reduced heat buildup while coating is intact
- ✅ Smoother, more comfortable cuts — especially important for pediatric patients
- ✅ Most economical coated blade option in the CC7/CC8 lineup
- ✅ 5-pack format — cost-effective supply for this specialist blade size
- ✅ 5-position rotatable mount — rotate to a fresh cutting edge to extend blade life
- ✅ Suitable for Plaster of Paris (Gypsona) and Polyester casts (Deltalite/Benicast/CellaCast)
- ⚠️ PTFE coating wears off after initial use — performance degrades toward uncoated stainless steel as the coating wears; monitor and replace promptly
- ⚠️ Not recommended for Fiberglass (Deltalite/Scotchcast)
🔵 Round vs. Segmented Blades — Which Do You Need?
| Blade Style | How It Cuts | Best For | Available Sizes (PTFE) |
|---|---|---|---|
| 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 precise cutting, better chip clearance | Pediatric casts; digits; tight anatomical areas; heat-sensitive patients | 32mm, 40mm |

📊 CC7/CC8 Cast Saw Blade Coating Comparison — Strongest to Weakest
The CC7 and CC8 systems offer four coating tiers. Understanding the 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) | 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 |
| #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) ← You are here | Spray-applied non-stick coating; low friction and reduced heat while coating is intact; tends to wear off after initial use — most economical coated option | Lower-volume practices; plaster and polyester; pediatric and digit casts; budget-conscious clinics |
💡 Need longer-lasting performance in this size? The 32mm blade is only available in PTFE coating for the CC7/CC8 platform. For higher-volume pediatric or digit cast work, consider rotating blades more frequently and keeping extra 5-packs on hand to ensure a fresh, fully-coated blade is always in use.

⏱️ When Should You Replace Your Cast Saw Blade?
A patient is always aware of a cast saw near their limb — and for pediatric patients and digit casts, this awareness is heightened. A blade that struggles to cut cleanly 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
Because PTFE coating wears off after initial use, monitor blade performance closely and replace promptly — don’t wait for visible wear. The 5-pack format keeps your supply stocked. 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 DeSoutter 19670 32mm blade used for?
The 19670 is the smallest blade in the CC7/CC8 lineup, designed for precision work in tight anatomical areas: pediatric casts, finger and toe casts, and thin single-layer applications where a larger blade would be impractical or unsafe.
Can the DeSoutter 19670 cut fiberglass casts?
No. The 19670 PTFE blade is not recommended for fiberglass casts. For fiberglass, use the Ion Nitride blade (part number 20280 for 64mm or 20290 for 80mm), which is the only DeSoutter coating recommended for fiberglass.
How long does the PTFE coating last on the 19670 blade?
PTFE coating tends to wear off after initial use, gradually degrading toward uncoated stainless steel performance. Monitor blade performance closely and replace promptly when cutting becomes less efficient. The 5-pack format and 5-position rotatable mount help maximize value.
Is the 32mm blade available in a harder coating like TiN or ZrN?
No. The 32mm blade size is only available in PTFE coating for the CC7/CC8 platform. For higher-volume pediatric or digit cast work, rotate blades more frequently and keep extra 5-packs on hand to ensure a fresh blade is always in use.
What is the difference between the 32mm and 40mm PTFE segmented blades?
The 32mm (19670) is the smallest blade for the tightest anatomical areas — fingers, toes, and very small pediatric casts. The 40mm (19700) is suited for wrists, forearms, short arm casts, and pediatric leg casts where slightly more cutting depth is needed.
