50x12x1.7mm Cutting Knife Carbide Blades With Three Holes Replacement

Product Description

Need a drop-in replacement for a worn trimming blade without buying a new cutter head? The 50x12x1.7mm carbide indexable blade is a solid tungsten carbide insert with three mounting holes, sized 50 mm x 12.0 mm x 1.7 mm. Loosen the clamping screws, lift the old blade, seat the new one and keep the cutter body. Blades ship 10 pcs per box in a protective plastic case, and customized sizes are supported on request.

A trimming station usually hits the same three problems: a chipped insert stops the line while a complete cutter head is ordered, a re-sharpened edge comes back at a slightly different angle each time, and a cutter body that is still sound is scrapped because the blade is not sold on its own. The 50x12x1.7mm carbide indexable blade is built to remove all three.

It is a replacement solid carbide blade, not a complete cutter. The insert measures 50 mm long, 12.0 mm wide and 1.7 mm thick, so it seats into an existing cutter body without machining, shimming or re-grinding the seat. Three holes take the original clamping screws and hold the blade in one fixed orientation, so the cutting edge returns to the same position after every change.

The blade is made from premium tungsten carbide, the material used for indexable woodworking inserts, so the edge stands up to abrasive glue lines, melamine and laminate. It cuts wood, plastic and other sheet materials, and the flat insert profile suits fine trimming and edge trimming work on edge banding lines.

Each box holds 10 pcs, packed in a protective plastic case that keeps the edges clear of each other in transit. Customized sizes are supported where a cutter body uses a different envelope. Origin is Guangdong Province, China; the price is quoted per order.

Product Features

What separates this insert from a plain flat blade:

• Exact 50 x 12.0 x 1.7 mm envelope - the insert repeats the original blade footprint, so it drops into the existing seat without filing.
• Three-hole clamping pattern - 3 holes spread the clamping load instead of one centre screw, and the hole centres index the blade to a single orientation.
• Solid tungsten carbide through the section - the blade is 1.7 mm of carbide with no brazed tip and no coating to wear through.
• Indexable single-blade design - a blade change means loosening the clamping screws and lifting the insert; the cutter body stays on the spindle.
• Flat 50 mm cutting edge - the edge runs straight along the 50 mm length and trims a flat band rather than a profile.
• Wood, plastic and sheet stock - one insert covers trimming on wood, plastic and other sheet materials, so a shop does not stock separate blades.
• 10 pcs per box - one box covers 10 blade changes, which keeps a spare within reach of the trimming station.
• Protective plastic case - blades are boxed in a rigid plastic case so 1.7 mm carbide edges do not knock against each other in transit.
• Customized sizes - length, width, thickness and hole count can be produced to a drawing when the cutter body is not the 50x12x1.7mm pattern.

Product Advantages

When an edge dulls you get two choices: send the cutter out and wait, or keep running a blade past its life and scrap parts. A box of inserts removes that choice.

• One insert, not one cutter head. A worn edge costs a single blade out of a 10 pcs box, not a complete replacement cutter.
• The edge lands in the same place. The 3 holes and the 50 x 12.0 x 1.7 mm body index the insert, so nobody re-sets the cutter after a blade swap.
• Minutes of downtime, not days. A change needs the original screws and a screwdriver; there is no machining, shimming or re-grinding of the seat.
• Consumable cost, not capital cost. Blades are ordered 10 at a time and kept at the station, so a chipped edge no longer waits on a purchase order for a whole cutter.
• Same trim on every batch. Because the blade is a fixed 50 mm insert rather than a re-ground one, the cutting edge geometry does not drift between batches.
• Spares that travel well. The plastic case holds 10 pcs, so a service technician can carry a full set of replacements in one hand.

Frequently Asked Questions

What size is this cutting knife?

50 x 12.0 x 1.7 mm, with 3 holes. The insert is 50 mm long, 12.0 mm wide and 1.7 mm thick, and the three mounting holes take the clamping screws of the cutter body it replaces.

Will it replace the blade in my current cutter body?

Only if that body takes a 50x12x1.7mm insert. Match the length, width, thickness and the three-hole pattern against the blade you are removing; if the pattern differs, order a customized size instead of forcing the insert.

How many blades come in one box?

10 pcs per box. Each box is packed in a protective plastic case so the carbide edges stay apart until the blade goes onto the cutter.

Is the blade solid carbide or steel with a coating?

Solid tungsten carbide. The insert is made from premium tungsten carbide, so there is no steel core and no coating layer to wear through at the cutting edge.

What does it cost and what is the minimum order?

Price is quoted per order. Send the blade size you need and the quantity, and we reply with price and order terms; customized sizes are quoted the same way.

Can I order a different size?

Yes. Customized sizes are supported, including a different length, width, thickness or hole count, when the cutter body does not take the standard 50x12x1.7mm blade.

What materials can it cut?

Wood, plastic and other sheet materials. The flat 50 mm edge is aimed at trimming and fine trimming work, which is where an edge banding line dulls a blade fastest.

Do I have to re-set the cutter after changing a blade?

No. The three holes and the fixed 50 x 12.0 x 1.7 mm body locate the insert in one orientation, so the cutting edge returns to the same position after the screws are tightened.
