The Difference Between Drill and End Mill

The Difference Between Drill and End Mill

Should I use a drill vs. end mill? It depends on what you’re attempting to attain.

Here’s an introduction of end mill anatomy, some fundamental cutter types, and suggestions on how to select the proper tooling for standard wood or plastic tasks.

Drill bits are created to plunge directly into the material, cutting axially and creating cylindrical holes. End mills are typically utilized for horizontal carving and cut laterally. Furthermore, most mills are “centre-cutting,” suggesting they are able to cut both axially and laterally. This is because of cutting flutes that encompass– and protrude from– completion face and enable plunge cutting. To lessen tool damage and tension on the material being cut, most CNC software will “ramp” completion mill slowly into lateral cuts.

On the contrary, end mills have main cutting edges located on the periphery of the tool body and auxiliary cutting edges situated at the bottom of the tool. An end milling can contain up to 16 cutting edges. For flat end mills, ideally, the feed can be provided in a direction perpendicular to the tool axis.


Twist drill and end mill cutter, although it seems to be the same spiral structure, there is much distinction between end mill and drill bit. The axial cross-sectional structure is various. Drill bit centre is extremely thin, steady thickening from the centre of the circle to the outer edge. Reducing the axial force of the axial borehole, and the axial cross-section of completion mill cutter is a solid circular in the middle, the external edge is a helical cutting blade. This structure figures out the end mill cutter can not shaft to the infeed; the structure distinction in between drill bit and end mill cutter, leading to the two different functions. The thick drill bit edge, the rotation of the cutting capability is really strong, so the drill appropriates for drilling; and the solid structure of the milling cutter, It appropriates for the transverse knife, but not axial infeed.

Finest Drilling End Mills

Below are Austgen’s list of drilling end mills for aluminium on the marketplace as reviewed by Australian G

eneral Engineering, your regional Melbourne based metal producer.

Router End Mills – Fish Tail
Fishtail points prevent any splintering or breakout and will plunge straight into your material producing a flat surface area.
These Router End Mills are ideal for plunge routing and producing accurate shapes– making them perfect for indication making and metal forming.

Engraving V-Bits
V-bits produce a “V” shaped pass and are used for inscribing, especially for making indications.
They come in a range of angles and pointer diameters. The little angles and suggestions supplied on these V-shaped engraving bits produce narrow cuts and small, fragile inscription of lettering and lines.

Helical Pointer– 4 Flute
The Helically Tipped Drill/ End Mill offers superior performance in chamfering, milling and light responsibility identifying operations. The spiral tip design enables for remarkable chip evacuation and surface finish.
