Features the K-Premium Safety Gauge shank!

2 flute, carbide tipped with bottom cutter insert for plunge cutting, (except for solid carbide router bits #17740 and #17750, which do not plunge cut). Items #17740, #17742 and #17744 are designed for European metric size plywoods. See chart below for undersize equivalency.

    Not so hot (3/5), Mar 1, 2020

    By John Kather (Carnation WA US)

    #17744 23/32" plunge cut straight bit was sharp and did the job at first but has quickly dulled after four or five uses cutting dado groves in cherry, birch , maple and plywood. The carbide got nicked easily as well - I'm guessing in plywood. After just using the bit today on cherry, it burned so bad it gets thrown in the dumpster. Not worth paying to sharpen and IMO not worth the extra$$. Ordering the standard plunge cut bit for a few bucks less.

    Bit sharpness (3/5), Nov 15, 2019

    By Troy (Wharton Te US)

    Bit was no sharper then MCLS bits and I saw no advantage. Maybe they will remain sharper for a longer term will just have to see. I ordered more bits from another vendor to test against the Katana bits. Maybe I will just return to using the MCLS bits I need to see if more expensive bits offer value for my money.

    Extremely SHARP (5/5), May 17, 2012

    By Eric (Middleton ID US)

    I ordered a set of these some time ago and was trying to get the little rubber thing off the first bit, but it was very stubborn. I gripped it very tight between thumb and forefinger and pulled hard. I immediately realized why they're called 'Katana'. A Katana is a Japanese sword of the highest quality blade. In the old days, Katanas were tested on prisoners condemned to death to see how many human bodies each blade would cut through in a single blow; this was how they rated each blade. The sharpest blades were '5 body blades'. The little rubber thing came off the Katana router bit, and I still had it between my thumb and forefinger, but the cutting edge of the bit had cut through the rubber and also through my the bone. I had to go to the hospital to get it stitched up. I asked the tech stitching it up if he could see the bone, but he said there was just too much blood. It required four stitches. I kept the hospital wrist band and put it inside the box that the router bits came in and to this day it's still there. These blades are extremely SHARP. Don't let your guard down; not even once. You've been forewarned.

    KATANA router bit (5/5), Apr 27, 2010

    By David G (Lincolnton NC US)

    Hi. Just thought I'd drop you folks a note about one of your product lines. Several weeks ago I purchased one of the Katana router bits, # 17756 and finally got a chance to use it today. WOW!!! All I can say is fanfreakingtastic. I've used other bits by different mfg's. with reasonably satisfactory results. This Katana bit however slices through this heavy Maple I have here in NC like it was cheddar cheese. I work mainly with tree stumps and slabs to make tables and let me assure you, some of this stuff is murder on a cutting edge. After approx. 2 hours of pretty much non-stop use, I took the bit off my router and noticed there was a good deal of pitch residue covering it. I normally clean my bits with store brand fume-free oven cleaner so I sprayed this one down and let it soak for about 15 mins. Hit it with some hot water and my scrub brush and it's clean as new. Also, (and this is what gets me), IT'S STILL SHARP ENOUGH TO SHAVE WITH!! Now THAT'S performance. None of my other bits can even come close to this. Even my Freud bit can't go for more than an hour maybe before it needs honing. I'm sold on the Katana bits from you guys. I'll be ordering again pretty soon as I want a couple on hand just in case I get some extra days to play in the shop.

    Katana 1/2" shank rabbet kit (4/5), Jan 19, 2020

    By Loring Chien (Katy TX US)

    I got this because it was the most complete rabbet kit from MLCS. Works well - the plastic box is a bit space wasting and oversize
    But I took off one star. It has every bearing for 1/16th steps except 1/16 and 3/16.
    I just built a small frame with a desinged 3/16 rabbet and when I went to get the kti out, found there was not combination for 3/16. Had to order the bearing (yes, MLCS does have a bearing of this size. WHy wasn't it in the kit?)
    And FYI, the bearing ID is 3/16th inch, critical info that's not written anywhere.
