1/4" cutting diameter, 2 flutes, single end, ball nose, long reach length, uncoated.
Ground from solid carbide. This tool cuts 1/4" diameter, runs a 1/4" shank, has 3/8" of flute and measures 4" overall.
The ball nose leaves a radiused bottom, which is what you want for 3D contours, fillets and mold surfaces rather than flat floors.
The necked long-reach body gets the cutting edge down into a deep feature while keeping the shank close to full diameter for rigidity.
Uncoated, so the edge stays as sharp as it can be ground — the usual choice for aluminum and other soft, sticky materials.
For HTC carbide tools, coating service typically adds 2–3 calendar days when the uncoated tool is available. If the tool is not in stock, estimated time to ship is 7–10 calendar days.
Estimated time to ship is measured in calendar days, from order placement until your order is handed to the carrier. Carrier transit time is additional. Orders may ship sooner. We accept orders awaiting replenishment; please contact us before ordering if you need a specific shipping date.
