Tooling and Accessories
Operation of the lathe requires certain basic
necessities such as cutting tools. Optional
accessories such as a 4-jaw chuck and milling
head extend the capabilities of the lathe to
perform advanced types of work. Safety gear,
such as safety glasses and eye shields help to
protect the lathe operator.
This section describes some useful
accessories and tooling for the SC4 lathe.
High Speed Steel Cutting Tools
For the home machinist and light industrial
user of the lathe, High Speed Steel (HSS)
cutting tools are used for most cutting
operations. Along with finished versions, these
tools can be purchased as blanks and ground
to the desired cutting shape using a bench
grinder.

Item # 22-501-102
Aside from low cost, the main benefit of HSS
tools is that specialized tool shapes can be
ground as needed for operations such as
chamfering, material cut-off and boring.
4-Jaw Independent Chuck
A 4-jaw chuck can hold stock with a square or
rectangular cross-section in addition to round
and octagonal stock. Unlike the standard 3-jaw
chuck, in which all of the jaws move together,
on the 4-jaw chuck the jaws adjust
independently, enabling them to clamp
irregularly-shaped stock.
4-Jaw Chuck
Item # 87-116-026
Adjusting the jaws individually makes it
possible to center a round workpiece, or a
reference point on an irregular workpiece, with
great precision. This feature is useful when a
workpiece has features on opposite ends that
must be machined on exactly the same axis.
Offsetting the workpiece also makes it possible
to drill off-center holes and to turn cam lobes.
Digital Caliper
Digital calipers are convenient measuring
tools for many lathe operations. They measure
outside and inside diameters as well as hole
depths to a resolution of 0.0005”. They switch
instantly between metric and inch units, so you
work in either format.

Center Drills
Center drills, also known as a drill &
countersink, are short and stiff and therefore
do not flex.
