Spiral up & down cut bits (5/5), Oct 15, 2008

By David I Gassner (LEBANON OR US)

I have used these bits many times, and have learned to love them. They cut quickly, and cleanly. I do not use strait bits near as often now.


Clean cutting spiral bit (5/5), Oct 15, 2008

By Marc Rea (Sierra Vista AZ US)

I needed a deep mortise in a table leg made of 2 sheets of 3/4" plywood laminated together. The 1/2" up spiral bit, number 7468, did great! With its 1 1/2" cutting length it had no problem reaching through the 1/2" template and through the 1 1/2" table legs! of course, I made several passes, but the bit cut like it was going through butter.

Excellent price for an outstanding bit! Get the set and get ready to route some mortises.


Upcut spiral (5/5), Oct 22, 2008

By Al Killian ( NY US)

Purchased one a few years ago for makeing groves for a project. It worked great. Used it yesterday to remove a profile off a door to replace the flat panel on the door. It made it easy to free hand without crabing or trying to take off.


5mm Shelf Hole Boring - Down Cut (5/5), Oct 22, 2008

By Christopher Hoxie (Lutz FL US)

If you are looking for 5mm shelf hole boring, they are hard to find. I did my research and these are the least expensive and of excellent quality. I am boring shelf holes in pre-finished birch veneered plywood using a plunge router @ 18,000 rpm. My cabinetry needs to have perfect holes and the down spiral bit does the job perfectly, although you need a good blow gun to clear the chips from the holes. Also, you must move the bit quickly because I got a little bit of burning in the hole if I lingered at all. I'm going to try turning the speed down some on the next set of cabinets. I've bored over 1300 holes so far with the first bit and even though there is a slight discoloration to the bit from heat build up, the holes are still perfect. I purchased some upspiral bits and although they left the hole chip free, the edge was slightly frayed and not good enough for me.
As for me, I will continue to buy my down spiral bits from MLCS until I "pony up" for a multi spindle boring machine and I imagine I will buy those bits from MLCS also.


Dadoes & Grooves (5/5), Nov 2, 2008

By Norman La Belle (Gurnee IL US)

I realize most folks use the spirals to cut mortises, which they excel at. I'm using a 3/8" spiral downcut to make dadoes or grooves in hardwood ply for casework, making the groove in 2 passes, adjusting the 2nd pass to EXACTLY size for ply shelving. A little more work? Yes. Worth it? Definitely, as the groove is sized correctly for the wacky thickness variables of ply, and the downcut bit leaves razor sharp edges to the ply with absolutely no tearout. When finished, it fits and looks great. Isn't that what we all search for?


Could be better - Don't know how!! (5/5), May 28, 2009

By John Schaben (La Crosse KS US)

Needed to bore some 5mm shelf pin holes so I was shopping for bits and ran across Mr. Hoxies' review on the downcut bit so I ordered one... Exactly as he said, perfect holes with no visible tearout. I haven't done any 1300 holes yet but my money is on this bit.


dulls quickly (1/5), Jul 8, 2010

By Bryan Becker (l.a. ca US)

I bought the 1/2" upcut spiral bit to cut 1 1/2" deep mortises in hard maple. Even taking 1/8" passes the bit chattered quite a bit. It strained on every plunge cut and dulled very quickly. I guess I'll have to pay $75 to get a decent bit.

MLCS NOTE: We do not feel that this is at all typical of the performance of our bits and this would certainly be covered by our MLCS product 3-year GUARANTEE.

1/4 " sprial flush down cut (5/5), Mar 28, 2009

By Ted Sisco (Bloomingdale nj US)

I bought the 1/4" down cut some time ago and I just had a chance to use it on some ply wood ,I can't think of any other tool that could make such a perfect smooth cut , now that I know how good this bit works , I am going to make a lot more projects with plywood and as soon as I'm done with this review ,I going to order another one.


Carbide Spiral Bits (5/5), Jul 7, 2012

By Jack Kreinbring (La Crosse Wi US)

I was a skeptic at first with these spiral bits. I was wrong. Using the upcut spiral bit with bearing in my router table makes smooth even templates cuts with NO SPLINTERING. Also the downcut spiral bit with bearing when used in my handheld router makes the the same smooth even cuts with NO SPLINTERING. Very very happy with the results and would recommend these bits.
Thanks MLCS

  • Compression Up / Down Spiral Router Bit

  • Reviews
Make clean cuts in composite sheet goods. This 2 flute solid carbide bit is needed to get clean, chip-free and splinter-free cuts in composite sheet goods such as Melamine or 2-sided Formica/Laminates and veneered plywood. The Up-shear/Down-shear design of the bit cuts toward the center of the sheet from both sides at once, saving time and eliminating waste.

Clean Cuts on Melamine (5/5), Dec 1, 2009

By Lee Wise (Prescott Ar US)

I just purchased this router bit as I am making all my garage storage cabinets from scratch. I had previously used a relatively good 80-tooth saw blade to cut melamine particle board for my shop cabinets. The tear-out was pronounced on the bottom and certainly visible on the top surface.

After reading about this product, I tried it, and it produced nearly flawless edges, top and bottom. It is definitely worth the extra time required to clean up the edges. I cut the pieces about 3/32 in. oversize, and then route the edges to size using a straightedge.

I highly recommend this bit!

Flush and Bevel Router Bits (1/5), Oct 22, 2008

By Christopher Hoxie (Lutz FL US)

I purchased several of both of these bits for my cabinet shop. I was very disappointed in the quality of the cut from these bits. If you are familiar with these type of bits, you know the cutting edge should be razor sharp causing it to be slightly recessed from the edge of the shank. These were not and in fact had a slight bit of the shank still at the edge of the grind. I think all six (kinda unlikely)of the bits must have been defective because every other product I've bought from MLCS has always been top quality. I'll contact them for a refund or replacement and see how their customer service is next.

MLCS NOTE: These bits were tested by our woodworker upon their return and appeared to cut fine.
