Descripción general

Las herramientas en espiral de corte descendente se utilizan mejor para materiales más delgados que serán empujados hacia la plataforma de la máquina en lugar de levantarse con una espiral de corte ascendente. Esto puede ser particularmente útil cuando se utiliza sujeción por vacío, donde es crucial mantener el sello entre el material y el lecho de sacrificio. Estas herramientas se utilizan principalmente cuando se requiere un acabado de corte de alta calidad en la superficie superior de las piezas cortadas.

Especialmente diseñado para proporcionar un excelente acabado. Se puede utilizar con enrutadores CNC, de mesa y portátiles.

Diseñado para cortar los siguientes materiales.

MDF/HDF	Tablero de espuma	Madera dura
El plastico	Madera blanda	Madera contrachapada

Frequently Asked Questions

What is a down-cut spiral router bit?

A bit designed to push chips downward, resulting in a clean top surface with minimal tear-out.

What’s the difference between down-cut, up-cut, and straight bits?

Down-cut: smooth top surface, rougher bottom
Up-cut: clean bottom edge, risk of top tear-out
Straight: general-purpose, less chip evacuation efficiency

What materials are best suited for down-cut bits?

Plywood, laminates, veneer, and finish-grade panels where a clean top surface is crucial.

When should I choose a down-cut bit over an up-cut?

When the top surface will be visible and needs to be perfectly clean (e.g., dados, grooves, or templates).

Are down-cut bits good for deep cuts?

Not ideal. Downward chip compression can cause clogging and heat buildup in deep cuts.

Do down-cut bits cause burning?

They can if chip evacuation is poor. Use multiple shallow passes and proper feed rate to avoid it.

How do I avoid overheating and bit wear?

Make shallow passes and avoid pushing the bit too fast. Ensure your router is powerful enough.

Can I use a down-cut bit for pocket cuts?

Yes, especially when the template is on the top surface — it helps prevent tear-out along the template edge.

Should I use down-cut bits in a router table?

You can, but remember the chip direction will push back toward the workpiece, so dust collection and safety are key.

What’s the downside of using down-cut bits?

Poor chip ejection on deep cuts. Not ideal for cutting all the way through thick material.

Awesome addition to my workshop tool storage

My router bits were spread out between three machines and my portable routers. I had them in drawers and in boxes. i now have them mounted next to the router table, pantorouter and cnc where they are in easy reach and i'll be buying a few more now that i know how easy they are to mount and use.

Good tool

Not much to say. Good tool at the decent price.

Compression bit

These are really nice! Well worth the price!

Wow!

Supersharp and fast enough for me. I run it at a spindle speed of 19000 rpm and feed of 20 to 30 mm a second. Works fine configured as a Vbit for making inlays. After roughing out with an upcut bit, this tapered ballnose goes trough like a knife through butter

Essential machine, 10 minutes to assemble it and you will see your boards super flat... excellent product and easy to use
