Providing state of the art results in flush trimming. The bit uses a double ball bearing pilot to run against your project template while the up cut flutes pull chips up and away from the router, leaving a smooth bottom surface.
TOOL SPECS: Solid carbide, upcut, flush trim spiral with 1/4″ cutting diameter, 1/4″ shank, 1″ cutting length, and 3″ overall length for use in routers with a 1/4″ collet.
FLUSH TRIM: For precise, clean flush trim cuts in hardwoods, laminates, plywood, particle board, solid surfaces, and composites for smooth results.
UP CUT SPIRAL: The spiral helix gently slices through wood grain to ensure clean, crisp cuts while outperforming standard straight bits.
TEMPLATES: For following templates, duplicating shapes, and creating intricate designs, especially when using a router table with the template positioned above the workpiece.
DOUBLE BEARING: Features double bearings for enhanced stability and reduced strain on the bearings.
Customers say
Customers praise the router bit’s smooth, butter-like cutting action and its effectiveness with repetitive parts. The bit is sharp, durable, and worth its price, with one customer noting it works well on 1/8″ aluminum sheet. However, durability receives mixed feedback – while some find it lasting, others report it falling apart quickly. Additionally, multiple customers mention issues with bearings coming off after about 5 uses.

Whiteside has won me over!
Let me start by saying I bought a crappy router set when I started woodworking with the plan of upgrading the bits to the better quality version as they wore out to spread the cost out over a longer length of time.Well it just so happens that my first few replacements were replaced with Freud bits. Im not a brand snob, I usually look for quality and price that match with reviews and Freud fit the criteria for my first couple bits. I’ve really had no problems with the Freud bits i’ve bought. They’re solid bits.But now it was time to upgrade my crappy straight flush bit and this time I decided to go with the Whiteside. I used it for the first time the other day and WOW. This is the most smooth, sharp, quality bit I own. It cut through my project like butter and left a silky smooth finish. I had pretty high expectations for this bit and it blew those expectations out of the water. Im highly considering just making all my future upgrades Whiteside bits. Seriously, I dont see how anyone can give this bit anything less than 5 stars. A++ bit

Smooth cutting bit!
It’s a great bit! The first one I received had to be returned due to the cutter leaving a mark on the wood…returned easily and without issue. The defect was just a one in a million type of things. These are great bits, great quality and smooth cutting! Will buy Whiteside again! …and again!

Game changer for template routing!
This bit is extremely sharp and cuts effortlessly. I bought it specifically for using on a table mounted router for routing using templates. With it being an upcut bit, when it is mounted upside down on a table mounted router it tends to pull the work downward. The spiral cutter pattern naturally tends to draw the work into the bit until the bearing makes contact with the template. I’ve always used template router bits with straight cutters which chip away at the wood. With those types of bits, I’ve always had to carefully trim away most of the excess wood before mounting my template in order to help prevent tear out and end grain blowouts. Not with this spiral bit! My first test cut was a 6″ interior hole that I needed to cut out of 3/4″ pine using my template I had already made. I drilled a 1/2″ hole inside the area I needed to cut out and tried cutting the 6″ hole without using a scroll saw to cut away the bulk of the material first like I normally have to do. I was able to cut the 6 inch diameter hole quickly and easily with this spiral bit. Not having to trim away the excess wood before using my template is going to be a huge time saver!

Not durable
1st cut nice and clean. Second cut, the bit broke in half. Durability is non existent. $45 for a router bit that lasted about 3 minutes is unacceptable. Iâm sure it works fine for pine and cedar but for hardwood, I would not recommend.

Does well on 1/8″ aluminum sheet
I skinned a trailer with 1/8″ aluminum sheet and used this to cut out the windows and doors along with trimming the edges. It’s done ~80′ of that material and still cuts. Pretty solid purchase for me.
