Making Holes is not new.

Some of the first holes using tools to create mechanical advantage were the Egyptians utilizing a hollow core bow saw.

We have been making holes since early man primarily for the purpose of assembly (put things together).

Pressingtechnology enablesmore range

The time and cost to produce a precision hole is amazingly quick.

The materials cut are also much more difficult to cut

3) Technology Range and Advantages

- Range of diameters and length of diameters

- Special geometries for problem solving

- Advantage of steel body vs solid carbide drill

Range of diameters and length of diameters

Small Diameters (4mm)

Options to go Deep

ComplexMulti-Operation

Special geometries for problem solving & high performance

Special geometries for problem solving

Resolve Stability issue with long extension ratios

Special geometries for problem solving

Vibration

Chip evacuation issues due to material or machine limitations

Special geometries for problem solving

Steel bodies allow for deflection to compensate for machine misalignment or non-flat surfaces

Steel bodies allow for drilling a range of sizes or boring by offsets

Steel bodies do not require length measurements and offsets when indexing inserts

Advantage of steel body vs solid carbide drill
