K315r

A direct replacement for the Esko BLD-SR6315, Gerber / MCT G42449504, and [BRAND TO CONFIRM] SE63R, with no holder modification needed. Single edge oscillating blade for through cutting on Esko and Gerber / MCT flatbed cutting systems.

Sold individually.

Direct OEM replacement

The K315r replaces the Esko BLD-SR6315, Gerber / MCT G42449504, and [BRAND TO CONFIRM] SE63R. Same 6mm round stock form factor, same geometry, same mounting. Drop it in and run.

What is through cutting?

Through cutting means the blade cuts completely through all layers of the material, including any backing or liner. The cut piece separates fully from the sheet. This blade is built for full through cuts. It is not a kiss cut blade.

Oscillating blade for demanding materials

An oscillating blade moves up and down at high speed as it cuts rather than dragging. This matters on thicker, denser materials where a drag blade would deflect or stall. Corrugated board, foam rubber, carpet, and sandwich board all benefit from the oscillating action. The blade cuts cleaner and lasts longer in these applications than a comparable drag blade would.

Fine grain tungsten carbide

Made from fine grain tungsten carbide. This is a harder, denser material than standard carbide, which means a sharper initial edge and longer edge retention across a production run. For materials like corrugated board, foam, and carpet that wear blades quickly, the carbide grade makes a real difference.

Common questions

How do I know this fits my machine?

If your machine currently uses the Esko BLD-SR6315, Gerber / MCT G42449504, or [BRAND TO CONFIRM] SE63R, the K315r is a direct drop-in. The 6mm round stock form factor is standard for these toolheads. Not sure? Contact us before ordering and we will confirm the fit.

What materials does it cut?

This blade is rated for corrugated board, foamboard, folding carton, felt, leather, display board, foam rubber, carpet, sandwich board, honeycomb, sandblasting mask, PET acoustic felt, varnish, and 3M VHB. Cutting something not on this list? Reach out and we will tell you if this blade is the right call.

What do the blade angles mean?

[TEAM INPUT NEEDED: Spec shows three angles (10° / 40° / 75°). Confirm whether these are three separate blade configurations, a cutting angle plus wedge angle plus relief angle, or another geometry. FAQ copy will be written once confirmed.]

How do I know when to replace it?

Watch your cut edges. Ragged edges, material dragging instead of separating, or corners not cutting clean are the first signs. When cut quality drops, swap the blade. Running a worn blade longer rarely saves time and often causes material waste or toolhead wear.

Getting the most from your cutting table

A fresh blade is a good start. But if you are going through blades faster than expected, or cut quality has become inconsistent, the blade is rarely the whole story. Cut depth, speed, pressure, and machine condition all affect how long a blade lasts and how clean it cuts.

It is worth asking: When was your machine last serviced? Are your parameters dialed in for this material? Is this the right blade geometry for what you are cutting? Could your operators use time with someone who runs these machines every day?
