Down Cut Single Flute End Mill

In applications when the top surface is highly susceptible to chipping or fracturing, the down cut spiral design is an excellent solution. This version maintains the forces downward instead of lifting, therefore reducing chipping or delaminating on surfaces. These tools should only be used in these unique applications and are not intended for regular milling.

This single flute tool machines non-ferrous materials at significant faster rates compared to conventional multi-fluted tools. The unique single cutting lip design has more relief and space for the chip to evacuate, allowing for faster feed rates and more throughput. These long-life, micro-grain carbide tools are available in various cutting diameters and lengths, shank diameters and geometries for specialty applications.

Datron’s unique cnc cutting tools are made with a proprietary process:

  • We use high quality Micro-grain carbide for longer tool life that saves you money
  • A multi-stage grinding process with extra sharp, polished edges for burr-free machining, reducing second operation costs
  • Patented tool geometries that decrease cycle times, improve finishes and increase throughput

Article #
The number of cutting flutes in the tool determine how much material can be removed per rotation. For high speed, bulk material removal, single and double flute are recommended. Higher flutes will produce finer finishes, but may require a lower RPM than single flute mills.
Flutes
D1
Nominal cutting diameter of the tool

Cutting Diameter
D2
Shank diameter where the tool is in contact with the holder. D2 diameter can be too large for some machine spindles and smaller diameters may need an adapter to be used with spindles.

Shank
D3= Toric cut diameter is the relief made above the cutting flutes on the neck to allow a tool to have longer reach when milling deeper features. Also known as extended reach.
(D3)
L1
L1 is the total length of the tool from tip to base.
Length
L2
L2 is the length of the usable cutting edge of the tool. This is only the flutes. Also known as flute length. This determines the amount (depth) of material that can be removed per pass.
Cutting Depth
L3
L3= This is the overall reach a tool can be used. Flute plus any relief made by reducing the diameter in D3. AKA known as reach
Reach
Radius of the cutting tip/nose.
Edge Radius
Angle
A= angle of a cutting edge. Drills, engraving tools and countersink tools aka point angle.
