Iscar Metals Inc. in early March presented a series of milling and drilling demonstrations during the company's 2020 Milling & Holemaking Seminar at its Tech Center in Charlotte, North Carolina.
Leading the seminar for Iscar were Craig Ewing, national product specialist for drilling, and Bryan Stusak, national product manager for milling. The two-day event focused on the impact cutting tools can have on higher profitability. Or, in Iscar shorthand, Profit LOGIQ.
Ewing and Stusak covered a wide range of tools for facing, shouldering, slotting, feed milling, profiling, plunging, reaming, tapping and boring. For the machining action, the program moved to the Tech Center shop floor where Iscar Tech Center Machinist Eric Dennis ran a series of cuts to demonstrate the maximum DOC as well as step over for each tool used.
In part one of CTE's coverage (displayed above), Iscar runs nearly 30 different cuts in a block of 4140 alloyed steel using a range of tools and tool lines:
- Heli12Feed upfeed line
- Heli3Mill HM390 line
- Logiq8Tang T890 milling line
- HeliTang T490 line
- Tor6Mill profiling line
- Multi-Master indexable heads
- Logiq4Feed high feed milling
- T-Face facemill
- TangFin finish milling
- NanMill nano endmill
- SumoCham
- Heli4Mill HM490 line
- ChatterFree solid mill line
- NanFeed nano feed mill
- Micro3Feed MF 300 endmill
In part two of CTE's coverage (coming soon), Iscar used the following tools and tool lines to demonstrate holemaking, again in a block of 4140 alloyed steel:
- Heli12Feed upfeed line
- SumoCham
- DR-Twist indexable drill line
- CombiCham
- BayoT-Ream
- Logiq3Cham three-flute chamdrill
- Multi-Master indexable heads
- ChatterFree solid mill line
- TriDeep deep drilling

Related Glossary Terms
- boring
boring
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
- endmill
endmill
Milling cutter held by its shank that cuts on its periphery and, if so configured, on its free end. Takes a variety of shapes (single- and double-end, roughing, ballnose and cup-end) and sizes (stub, medium, long and extra-long). Also comes with differing numbers of flutes.
- facemill
facemill
Milling cutter for cutting flat surfaces.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- milling
milling
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
- profiling
profiling
Machining vertical edges of workpieces having irregular contours; normally performed with an endmill in a vertical spindle on a milling machine or with a profiler, following a pattern. See mill, milling machine.
- slotting
slotting
Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.
- tapping
tapping
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
