Stryker Cast Cutter Saw Blade 940-25 Stainless Steel

Stryker 940-25 Stainless Steel Cast Cutter Saw Blade

The Stryker 940-25 Stainless Steel Cast Cutter Saw Blade is designed for use with the Stryker 940 cast cutter saw. This high-carbon stainless steel blade is ideal for routine cast removal in orthopedic clinics, hospitals, and casting labs.

After Stryker shut down cast saw support in the USA, many facilities were left scrambling for reliable blades and accessories. OrthoTape worked directly with Stryker’s global partners to secure authentic, compatible blades that can still be shipped into the United States, so your Stryker 940 cast saw stays in service.

Stryker Cast Saw Support Update

Stryker recently shut down all cast saw support in the United States, including blades and accessories. Because Stryker products are still sold globally, we contacted Stryker and confirmed two overseas manufacturers that continue to produce authentic Stryker-compatible blades. We now import these blades and stock them in our Ridgeland, SC 29936 warehouse for fast shipping within the USA.

What Type of Blade Is This?

This specific product is a stainless steel, uncoated Stryker 940-25 cast cutter saw blade. It is made from high-carbon stainless alloy that is heat-treated for durability and consistent cutting performance. Stainless steel blades are the standard choice for general orthopedic use.

Below is an overview of common cast saw blade coatings you may see when comparing blades for the Stryker 940 or other cast cutters. These are listed from strongest coating to standard stainless steel.

Cast Saw Blade Coatings – In Order of Strength

#1 Dichronite Blade (Coated)

Dichronite (Tungsten Disulfide) is a dry-film lubricant applied to stainless steel blades under high air pressure. The coating bonds tightly to the metal, creating a very slick, low-friction surface. Benefits include:

• Extended blade life
• Cooler cutting temperatures
• Reduced drag through cast material

#2 Ion Nitriding (Coated)

Ion Nitriding, also called “plasma coating,” uses electron bombardment of nitrogen ions in a vacuum chamber to harden the blade surface. This process produces:

• Surface hardness approaching that of diamonds
• Very smooth surface with extremely low drag
• Maximum blade life for high-volume cast removal

#3 Titanium Nitrided Blade (Coated)

Titanium nitride is a gold-colored “ceramic” coating applied to a stainless steel base blade. Once applied, it:

• Hardens the cutting surface
• Reduces friction and drag
• Helps maintain sharp teeth and cooler surface temperatures

#4 PTFE (Teflon-Coated)

PTFE (Teflon) is a very slick, non-stick coating sprayed on at room temperature and then cured. It allows the blade to slide smoothly through casts with low resistance. However:

• The PTFE coating can wear off relatively quickly
• Performance may decline once the coating degrades

Even with this drawback, PTFE-coated blades remain popular because of their initially low friction surface.

#5 Stainless Steel (Uncoated)

Stainless steel blades (like this Stryker 940-25 blade) are not coated. Instead, they are made from high-carbon stainless alloy that is tempered using a high-temperature hardening process. This:

• Makes the steel much harder
• Helps the teeth stay sharp longer
• Provides reliable performance for routine cast removal

Over time, the teeth gradually lose sharpness, which increases cutting time and friction. A very dull blade can generate enough heat that the patient may feel warmth even through cast padding.

How Long Does a Stainless Steel Stryker 940-25 Blade Last?

As a general guideline, a normal orthopedic practice that removes around 10 casts per week can expect a single stainless steel blade to last about 1–2 months before it should be replaced.

How to Choose the Right Cast Saw Blade Coating

1. Estimate your cast removal volume.
   High-volume clinics often benefit from coated blades (Dichronite or Ion Nitriding) to maximize life and reduce heat.
2. Consider patient comfort.
   Coated blades generally run cooler and smoother through the cast, which can help reduce patient anxiety.
3. Balance cost vs. longevity.
   Stainless steel blades are more economical up front, while coated blades cost more but typically last longer.
4. Match your saw model.
   Always confirm that the blade is compatible with the Stryker 940-25 cast cutter saw before ordering.
