Sherline Lathe User Guide and Specifications

The shaping of cutting tools to suitable angles for the type of material and nature of work
being performed can be very important to satisfactory work. When tools become dull,
gently re-grind and preserve the original angles and shapes. Do not grind the top face of
the tools, but confine sharpening to the end and/or sides except form tools which are
ground on the top surface.
Remember that heavy cuts and rapid feed will cause greater strain on the chuck and lathe.
This may induce "spring" or binding of work and tools which can produce a poor finish.
NOTE: Because of the importance of a sharp and properly ground tool to the cutting
process, Sherline has prepared a special instruction sheet on Grinding Your Own Lathe
Tools. There are a few tips that can make the process a simple one. The instructions are
included with each lathe and with cutting tool sets when you order them from us, or you
may call us and request a copy. (Cost is $5.00 postage paid.) They are also available from
our World Wide Web site by clicking on the highlighted words above.
FIGURE 11—Tool Shapes.
*These shapes are available in high speed steel tool set, P/N 3007.
**The 60° threading tool is included as part of the carbide tool set, P/N 3006 and also
comes with the thread cutting attachment, P/N 3100.
***The parting tool comes with the cutoff tool holder, P/N 3002. Other shapes are
custom ground to accomplish special purposes as needed.
Cutting tools are ground to various shapes according to their usage. Tools are usually
ground to shape as needed by the operator. Some standard tools are described below:
Normal Turning Tool—This feeds from right to left, is used to reduce work to the
desired diameter and is the most frequently used of all tools.
Side Tools—These are used to face off the ends of shoulders and may also be used as
normal turning tools. Note that a tool which is fed from LEFT to RIGHT is called a
LEFT side tool.
