SMART CUT® 105N Diamond, Nickel Bond Wafering Blades INTERRUPTED RIM

The SMART CUT® 105N features an interrupted rim design, which allows for freer and more aggressive cutting compared to continuous rim nickel bond wafering blades. The interruptions in the rim help reduce heat buildup and minimize loading, making these blades ideal for cutting softer, gummy, or fibrous materials.

This blade is designed for cutting a wide variety of materials, including:

• Micro-electronics packages
• PCB boards
• Plastics & composites
• Soft and precious metals
• Fish and human bones
• Graphite & electro carbons
• Glass-reinforced plastics (GRP) and FR4
• Pre-sintered & pre-fired (green) ceramics
• Soft ferrites

Nickel bond (electroplated) blades have a single layer of diamonds held by a tough and durable nickel alloy. Unlike sintered (metal bond) blades, where diamonds are embedded inside the metal matrix, nickel bond blades have exposed diamond particles that protrude from the bond. This ensures:

• Faster and freer cutting
• Minimal heat generation
• Reduced loading and glazing issues
• More precise and clean cuts

SMART CUT® technology ensures that:

• Only the active diamond layer is in contact with the material. As the bond wears down, new layers of diamond are immediately activated.
• Each diamond particle is placed strategically to optimize cutting efficiency.
• The cutting edge remains sharp longer, ensuring consistent performance throughout the blade’s lifespan.

The standard arbor size for the SMART CUT® 105N blade is ½” (12.7mm). However, we can modify the arbor size to any specification on the same day for a small additional fee.

The core steel used in these blades is engineered with memory properties, meaning that even if the blade bends during use, it snaps back to its original shape. This prevents deformation, ensuring consistent accuracy and precision over time.

Nickel bond blades differ from sintered metal bond blades in several ways:

Yes. The SMART CUT® 105N wafering blades are designed for high-precision cutting applications in microelectronics, medical, and research industries, where minimal chipping and clean edge finishes are required.

The SMART CUT® 105N Nickel Bond blade differs significantly from resin bond diamond wafering blades in several ways:

➡ Use the SMART CUT® 105N if you need high-speed cutting of soft and gummy materials without loading or glazing issues.
➡ Use a resin bond blade for ultra-smooth finishes on hard, brittle materials where controlled wear is needed.

Yes, the SMART CUT® 105N is well-suited for cutting multi-layered materials, including PCB boards with embedded metals, composites, and laminates.

• The interrupted rim design reduces heat buildup, preventing delamination of PCB layers.
• Nickel bond diamond exposure ensures efficient cutting of both the resin and metallic layers within the board.
• Recommended Cutting Method: Use wet cutting with an appropriate coolant to avoid excessive heating, which could degrade the epoxy resin in PCB boards.

The maximum cutting depth depends on the blade diameter and material being cut:

Important Considerations:

• For deep cuts, multiple passes with progressively deeper cuts are recommended to avoid excessive blade stress.
• Coolant is required to prevent overheating and material damage.

Yes, but with several limitations:

• Dry cutting is not recommended for prolonged use due to heat buildup, which can damage both the blade and the material.
• For short, shallow cuts, dry machining may be possible, especially with softer materials like graphite or PCB boards.
• If dry cutting is unavoidable, reduce feed rates and use intermittent pauses to allow the blade to cool between cuts.

✅ Best for: Short, non-continuous cutting applications where coolant use is not feasible.
❌ Not recommended for: Continuous cutting of heat-sensitive or thermosetting materials.

• Low-Density Graphite: The blade cuts extremely fast with minimal resistance. Recommended lower RPMs to prevent over-aggressive cutting.
• High-Density Graphite: More challenging due to increased hardness. Wet cutting with coolant is required to prevent excessive wear.
• Electro-Graphite: Can be abrasive on the blade, so reducing feed rate and applying proper cooling is recommended.

➡ In all cases, an interrupted rim design helps reduce material loading and improves chip clearance.

Yes. Proper clamping ensures minimal vibration, better precision, and reduced chipping when cutting FR4 (PCB material) or GRP (glass-reinforced plastic).

• Use vacuum or mechanical clamps to hold thin sheets securely.
• Avoid excessive force, as it may deform or crack the material.

For small or fragile pieces, consider mounting them onto a sacrificial substrate to reduce stress.

The best coolant depends on the material:

• Water-soluble coolants – Best for general cutting (e.g., PCB boards, plastics, FR4).
• Oil-based lubricants – Recommended for metals and soft ferrites to prevent oxidation.
• Deionized water – For graphite and electro-carbons, avoiding contamination.

• Water-based coolants are the best choice for most applications.
• Oil-based lubricants are recommended for cutting soft metals and ferrites, as they provide better lubrication and heat dissipation.

➡ Avoid using pure water without additives, as it may lead to corrosion of the blade core.

• Coolant significantly extends blade life by reducing friction, heat, and material buildup.
• It prevents diamond pull-out by keeping the blade’s nickel bond intact longer.
• Using improper coolants (e.g., pure water without additives) can cause rusting, shortening blade lifespan.

A steady and consistent coolant flow is recommended.

Signs of blade wear include:

• Increased cutting resistance
• Reduced cutting speed
• More chipping or burrs
• Visible diamond loss on the blade edge

Dressing helps remove debris and refresh the diamond surface, improving cutting efficiency and extending blade life.

For nickel bond blades, a medium to fine-grit aluminum oxide dressing stick is recommended.

• Resin buildup reduces cutting performance by clogging diamond edges.
• Can be prevented with proper coolant and occasional blade dressing.

Nickel bond blades offer:
✔ Lower initial cost than sintered blades
✔ Higher cutting speed, reducing per-cut costs
✔ More aggressive cutting than resin bond, reducing cycle time

• When a smoother surface finish is required (e.g., optical applications).
