Self Adjusting Boring Bar Packing

High temperature chevron packing is spring-loaded to insure positive, leak proof sealing without packing adjustments. Line pressure does not enter case.

Rugged Construction

All working parts totally enclosed to permit complete lubrication and to prevent damage from dirt or other foreign material and from rough handling.

Handling Ease

Telescopic arrangement of working parts adds strength and rigidity and greatly reduces overall length and weight.  Conveniently placed handles, eyebolt and lifting yoke permits easy handling of the machine - manually or with hoisting equipment

Automatic Feed

Machines include a positive automatic feed during the cutting operation.

Feed Indicator

Easily set feed indicator shows amount remaining to be cut when in automatic feed.

Rapid Hand Travel

When not cutting, the boring bar may be quickly and easily advanced or retracted by hand.  Rapid advancement and retraction of the boring bar reduces time of operation.


Tools are available for making lateral connections using tapping sleeves and valves, gate valves or standard fittings in cast iron pipe, concrete pipe and steel pipe.

Capacity and Use:

The CC-25 Drilling Machine is hand operated for making cuts from 2" to 12" inclusive in any size of main.  this machine has automatic tool feed and is equipped with feed indicator.

Used with MUELLER Tapping Sleeves and Valves, Gate Valves or standard fittings, it will make cuts 2" to 12" inclusive under pressure for lateral connections.

Used with Proper MUELLER equipment, it will inset a 4", 6", or 8" special MUELLER Gate Valve into a main of equal size under pressure.

Working pressure and Temperature:

500 p.s.i. Maximum Working Pressure at 100℉, 500℉ Maximum Temperature Rating at 250 p.s.i.

The working pressure or temperature rating is reduced accordingly if any attachment, valve or fitting subjected to pressure or temperature during the drilling operation has a maximum working pressure or temperature rating less than that specified above.

Length of Travel:

25" - This is adequate for all sizes of MUELLER Tapping Sleeves and Valves, and MUELLER Inserting Valves within the capacity of the machine.

* These tools, marketed CEM-RES, are for use with cement-lined cast iron pipe. They may also be used for asbestos-cement pipe.
** The Shell Cutters and Pilot Drills are tungsten Carbide Tipped to provide a strong sharp cutting edge which will resist abrasive action encountered when cutting concrete pipe.  When cutting concrete pipe these tools must be power operated.  We also recommend these tools for cutting asbestos-cement pipe, cement-lined cast iron pipe and cast iron pipe, because they will make a greater number of cuts before sharpening.  For asbestos-cement pipe, tools may be hand operated; however, they should be power operated when cutting cement-lined cast iron pipe. The outside diameter of the Shell Cutters is 1/2" less than the nomial size of the tapping valve.  This undersize design greatly reduces the wear on the outside edge of the shell cutters when making a lateral connection the same size as the main being cut and reduces travel required to complete cut.

* This is the maximum working pressure of the adapter at 100℉. This is working pressure must be reduced accordingly if any attachment, valve, fitting or machine, subjected to pressure during the use of this adapter, has a maximum working pressure less than that specified above.
NOTE: When using these adapters with standard gate valves, check to be sure there is sufficient trave to complete the cut if special fittings are used to attach the gate valve to main being cut.
