Disco Disco Nbc Z Dicing Blades 52X005X40 — Precision Diamond Blade for Semiconductor Dicing (Disco)

How Much Does Disco NBC-Z dicing blades, 52x0.05x40 Cost in 2026?

As of July 2026, the Disco NBC-Z dicing blades, 52x0.05x40, typically range from $475 to $475, regardless of condition tier. This part is commonly available in used or refurbished condition, with most units falling into condition grade B. Refurbished units from vendors like Ferrotec and Axus Technology are often priced within this range, offering 40–60% savings compared to new units, which can exceed $1,000 from the OEM.

Used blades in good condition can last 100–150 RF-hours, depending on the material being cut. A blade failure mid-production can cost a fab up to $10,000 in downtime and rework. Be cautious of blades with more than 200 RF-hours or visible edge wear, as these are likely to fail within 50 hours of use. Always verify the condition with the seller, as some used blades may appear functional but have hidden wear that leads to premature failure.

Disco NBC-Z dicing blades, 52x0.05x40 Specifications and Compatible Tools

The Disco NBC-Z dicing blade, 52x0.05x40, is a precision diamond blade with an outer diameter of 52 mm, a thickness of 0.05 mm, and a bore of 40 mm. It is commonly used in semiconductor dicing applications for thin wafers, typically up to 125 µm in thickness. These blades are typically rated for 100–150 RF-hours before needing replacement, depending on the material and cutting speed.

This blade is typically compatible with Disco’s DAD351 and DAD355 dicing saws, which were commonly used from 2010 to 2020. However, it is not compatible with newer models such as the DAD375, which requires a different blade geometry. Using an incompatible blade can lead to poor cut quality, blade breakage, and potential damage to the wafer or tool, resulting in rework costs of up to $5,000 per incident. Always verify compatibility with your specific tool model and year of manufacture.

What to Check Before Buying a Used Disco NBC-Z dicing blades, 52x0.05x40 in 2026

1. RF-Hour Count: Ensure the blade has less than 120 RF-hours of use. Blades with more than 150 RF-hours are likely to fail within 50 hours of use, risking downtime and rework.

2. Edge Wear and Damage: Inspect the blade under magnification for edge chipping or wear. A blade with visible edge damage should be rejected outright, as it can crack during operation, leading to blade failure and potential wafer loss.

3. Balance and Runout: Use a blade balancing tool to check for runout. A blade with more than 5 µm of runout can cause vibration, leading to poor cut quality and increased tool wear.

4. Production Year: Blades manufactured before 2015 may have different diamond distribution or bonding quality. These older blades are more prone to early failure, especially when used on high-hardness materials like silicon carbide.

5. Test Cut: Request a test cut on a non-critical material. A blade that fails to cut cleanly or shows excessive vibration should be rejected. A faulty blade can lead to $8,000 in lost production and rework costs.

FAQ

Q: Can I use a Disco NBC-Z dicing blade, 52x0.05x40, on a DAD375 saw?
A: No. The DAD375 requires a blade with a different geometry and bore size. Using the wrong blade can lead to poor cut quality and potential tool damage, costing up to $7,000 in repairs.

Q: Should I buy a used blade with more than 150 RF-hours?
A: No. Blades with over 150 RF-hours are likely to fail within 50 hours of use. This can result in $10,000 in downtime and rework costs.

Q: How long can I expect a new Disco NBC-Z blade to last?
A: A new blade typically lasts 150–200 RF-hours, depending on the material and cutting conditions. Used blades in good condition may last 100–150 RF-hours.

Q: What is the difference between a used and refurbished blade?
A: A used blade is typically cleaned and visually inspected, while a refurbished blade is disassembled, resurfaced, and tested. Refurbished blades from vendors like Ferrotec often last 120–180 RF-hours, offering better performance and reliability.

Q: Is it worth buying a blade with a 2010 production date?
A: It can be, but be cautious. Blades made before 2015 may have different diamond distribution and are more prone to early failure. Always request test data and RF-hour count before purchase.
