Sherline 3005B 1/4 Inch HSS Tool Blanks (Set of 5)
Lathe tools, or tool bits as they are sometimes called, are the cutting tools that are used for turning and facing work on the lathe. The most popular lathe tools are those made of high-speed tool steel (HSS). They can be used for machining most materials including wood, plastic, aluminum, brass and steel.
These tools will retain their hardness at temperatures up to 1000° F. (588° C.). For this reason, depth of cut, cutting speed and feed rates are important. The big advantage of high-speed steel tools is the ease with which they can be sharpened. A standard aluminum oxide grinding wheel can be used. Once shaped and sharpened, they will retain their cutting edge for a long time.
Provided with each Sherline lathe is a pre-sharpened 1/4″ HSS cutting tool.. Pre-sharpened tools are also available in sets with a right-hand, left-hand and boring tool pre-ground for you. However, it is much more economical to learn to grind your own tools starting from a blank. You can save specially ground tools for similar jobs in the future or re-grind them for another use. The tool blanks can be purchased singly or in packages of five.
Each tool bank measures : ¼ x ¼ x 2-1/2
Carbide lathe tools usually have a tungsten carbide cutting tip
brazed or bonded to a softer steel shank. These tools are
recommended for cutting hard or abrasive materials. Carbide tools
can retain their hardness at temperatures up to approximately
1700°. This permits a higher cutting speed and faster feed
Carbide tools are typically harder to sharpen than their high
speed counterparts. A silicone carbide grinding wheel or diamond
wheel must be used. The shape of a carbide tool is more critical
than the shape of a high speed tool steel cutter. As long as the
edge of a high speed steel tool is kept sharp it will usually
perform quite well. Carbide tools, on the other hand, may be prone
to chipping and cratering if the cutting angles are not proper.
SHERLINE recomends the use of high speed steel tools whenever
possible. It is also recommended to learn to shape and sharpen high
speed tools if you have any exotic projects in mind. An inexpensive
grinder with good quality wheels and a wheel dresser is all that is
A grinding attachment would be an easy accessory for SHERLINE to
manufacture; however, because of the damage that could be done to
your fine tools with the grinding dust, we recommend buying a
separate grinder. SHERLINE has no plans to make this type of
accessory. If you use a grinder, protect your other tools from the
abrasive dust by covering them or by doing the grinding in another
SHERLINE Cutting Tool
SHERLINE supplies lathe tool sets in either high speed steel or
carbide materials. In either case the set contains three tools: a
left hand cutting tool, a right hand cutting tool and a boring tool
for the high speed steel set or a threading tool for the carbide
set. In view of the low cost of these tool sets, it is a good idea
to have one of each on hand.
