At The M. K. Morse Company we’ve had just one focus for over forty-five­
years. Make better saw blades and accessories and get them to customers on time. We don’t make machinery. We don’t make other products.
We do one thing and we do it very well.
This single-minded devotion has led to some unique innovations over the
years. But, mostly it has led to a relentless march to improve value.
We are constantly looking for ways to build even more durability into our
blades while driving production costs down. The result is a line of high
value industrial band saw blades that top the charts in performance and
quality.
We have accomplished this by totally integrating our manufacturing
process. In fact, we do everything but make our own steel ... so far. This
unique ability to control our processes makes it easier for us to meet tight
production deadlines and control costs. Our customers get the benefits.
At M. K. Morse this is the way we operate.
There really was an M. Kenneth Morse. As a manufacturer’s rep, he became frustrated when he sold
products manufacturers couldn’t deliver on time
or with the quality his customers demanded. He
started manufacturing saw blades to make sure
his customers got what they wanted when they
needed it. We still do business the same way
today, using the talents and resources of people
working in manufacturing and warehousing facilities around the world. They are M. K. Morse, today.
We’re still headquartered where we started ... in Canton, Ohio, U.S.A.
However, today we have warehousing in Los Angeles, California;
Vancouver, Canada; Toronto, Canada; West Yorkshire, England; and
Helsinki, Finland. The Los Angeles, Toronto, and West Yorkshire warehouses are also weld centers. Our products are available from industrial
supply distributors world-wide.
Our reputation for immediate availability at all distribution facilities
and timely shipment is based on solid facts. Over 98% of all orders for
standard stock products ship complete within 24 hours. Our integrated
manufacturing process, dedication to customer service and worldwide
distribution make it all possible. Our customers make it all worthwhile.

Tension gauge FEATURES
• Durable cast/powder coated body
• Calibrated gauge measures in lbs/in2
as well as kg’s/cm2
• Quality storage box with protective
foam inserts
benefits of proper
blade tension:
• Optimal blade life
• Precise cutting results
• Reduces the occurrence of
machine damage due to
blade over-tensioning
Blade Break-In: Extremely Important
The extremely sharp tooth points and edges of new blades must be
broken-in before applying full feed pressure to the blade. A good
analogy is that of writing with a freshly sharpened wooden pencil.
Recommended Break-in procedure
• Maintain proper blade speed for the material to be cut.
• Reduce blade feed pressure or feed rate by 50% for the first
50 to 100 square inches of material cut.
• Gradually increase feed pressure or feed rate after break-in to full pressure or rate.
Warning About Blade Usage
CUTTING TOOLS CAN SHATTER AND/OR BREAK UNDER IMPROPER OR SEVERE USE. WEAR SAFETY EQUIPMENT, AND PARTICULARLY GOGGLES, GLOVES AND HEARING PROTECTION, AT ALL TIMES IN THE VICINITY OF THEIR USE. ALWAYS FOLLOW BAND SAW MACHINE MANUFACTURERS’ RECOMMENDATIONS.

A Change to M. K. Morse Band Saw Part Numbers
18
The M. K. Morse Company has begun using 10-digit numeric band saw blade part numbers rather than
alpha-numeric part numbers.
The first 6-digits of the part number identifies the material and size specifications. The last 4-digits identifies
the length of the blade for both weld-to-length bands and coil stock.
The following band saw blade part number reference chart provides the same details we have in-house to
configure the new part numbers. Customer Service at M. K. Morse will be able to assist all band saw blade
distributors with any cross referencing needed. We are providing this information so that our distributors
are informed and have all available information. If you have any questions, please contact your M. K. Morse
Customer Service Representative.
The M. K. Morse Company will provide bi-metal and carbon weld-tolength blades on a “Guaranteed Billed Trial Blade Basis” for the purpose
of user evaluation of performance. If the blade recommended by Morse
or approved by Morse for the particular application, fails to perform satisfactorily for the user, Morse will issue a full credit for the invoice value
of the blade upon the return of the blade to Morse.
In all instances where Morse provides bi-metal and carbon welded-tolength band saw blades for trial and evaluation, the Morse sales representative will provide follow-up.
Morse is confident in the ability of our blades to meet the end users expectations for performance.

Anatomy of a Saw Blade
Although it looks like a flat piece of metal with teeth, a quality industrial band saw
blade is actually a sophisticated cutting tool. Its ability to efficiently cut through tough
metals, composite materials, plastics, and woods depends on a variety of interrelated
factors such as the design, spacing and set of the teeth; the design and capacity of the
gullets to make sure chips are efficiently removed; the composition of the backer strip;
and the gage of the metal. These considerations must be taken into account when
selecting the right blade for your application. The following Technical Pages will help
you arrive at the perfect Morse solution to your particular cutting problem.

Here’s where the blade makes the cut. The tooth design variables include shape,
position, set, type and spacing. The combination of these variables will determine
whether the blade can move easily through your material without binding or
becoming clogged with chips.
