10 Reasons to Use Flat Bottom Tools. Flat bottom tools, or tools with flat bottom geometry, are useful in a variety of a situations and operations that tools with typical cutting geometry are not. The standard characteristics of drills or end mills are useful for their primary functions, but make them unsuitable for certain purposes.

Plunge milling operations vary considerably from traditional milling. They use the end of the tool to cut instead of the periphery, which beneficially changes the cutting forces from a predominantly radial to axial direction. It can be compared to a boring operation with interrupted cuts. Power consumption and noise are low.

A typical end mill may be referred to as an "Upcut Spiral" by the CNC Router world. Other than small geometry changes to optimize for wood, end mills and upcut spirals are interchangeable. The more common spelling is "end mill", but I often use "endmill" as well. The two are pretty interchangeable. Carbide vs HSS End Mills

The flat bottom holes are nothing critical, only clearance for a bolt head. I have been a machinist for over 30 years but this was on manual machines such as cincinnati verticals and g&L horizontal boring mills. On these machines I would put in 1 1/4" flat bottom holes using a 1 1/4" 2 flute high speed endmill and just plunge it right in.

A special class of end mill is termed the slot drill. This is a cutter intended for slotting and keyway cutting. It is provided with end cutting edges which are offset about the centre, so that the longer cutting edge passes slightly over the centre, allowing plunge cutting into the work.

For a flat bottom, just drill to size and clean up the bottom with any center cutting endmill - thats the easiest. Two flute center cutting can be plunged more easily than four flutes and if you have a dinky mill its hard to get an accurate sized hole making a plunge cut with an endmill.

Can an end mill plunge? Most end mills have cutting edges on the bottom face which will let you plunge into your material. Plunging is usually done at a slower feedrate than when milling along the X and Y axes and avoid going too deep before …

Use these end mills for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. They have a square end for milling square slots, pockets, and edges.. End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with …

Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations.

Todays carbide end mills that are center cutting - and with a little dish - (I think there is a 3-5 degree dish) - will plunge, but inefficient chip removal - the bottom of the hole will sorta look flat. With a HSS end mill that is not center cutting "might" plunge but smoke badly and leave a mess in the bottom of the hole.

This may require flat-bottom tooling such as end mills or twist drills that are specially made for Plunge Milling. Not the Best Under Favorable Conditions: Plunge milling is not a general-purpose strategy that replaces all other strategies. It's best use is when you need plunge milling's advantages: more rigidity and less power required.

A drill bit is designed to plunge directly into the material and create holes only, while an end mill can cut laterally into the material and create slots or profiles. Besides, most end mills are designed to be centre-cutting, meaning they can plunge into the material as well and making them far more versatile than drill bits.

They cut best using the side of the mill, so most cutting software will slowly ramp the end mill down into the material, rather than a simple plunge. With fishtail end mills, you will have nice square corners at the bottom of any inset section of geometry and a smooth, flat surface anywhere it passes over the top of.
