B-100

Fast taps, pressure tight connections and easy trouble-free operation provide an operating efficiency so necessary to meet today's demands.  The new B-100 Drilling, Tapping, and Inserting machine gives these results IMMEDIATELY and CONSISTENTLY.

The machine incorporates the same basic double pressure chamber, single boring bar design principle which, through 90 years of field experience, research and testing, has proved to be the most efficient in operation.  Its design permits the operator to handle the machine in lightweight sections.  The tapping and inserting operations are performed separately.  Tool or stop may be safely removed from the machine at any time during the operation for inspection or replacement, if necessary.

The "B-100" is all new from the saddle up, and has plus features we know you have wanted.  Look over these features... see how they all combine to contribute to faster taps, pressure tight connections and easy, trouble-free operations.

• Anti-Friction Thrust Collar - sandwich type nylon-"teflon"-nylon bearing sealed in steel case; no lubrication; won't gall under power operations.
• Feed Nut and Yoke - spring detents hold feed yoke securely in place around boring bar; acme threads; square shank on feed yoke fits power operator for automatic feed.
• Easy Operating Ratchet Handle - fully enclosed; lubricated; quick-reverse button; lightweight.
• "O" rings Eliminate Packing Adjustments - provide oil reservoir for lubricating boring bar and "O" rings. Boring bar wiper protects bottom "O" ring.
• Feed Sleeve and Cap - quick removal; acme threads, only 2 1/2 turns to remove; long bearings give maximum boring bar rigidity; positive metal-to-metal contact with cylinder; "O" ring seal.
• Chrome Plated Boring Bar - won't corrode - assures long life of "O" ring seals.
• Offset Body Design - reduces collection of chips around flop valve when using machine in horizontal or inclined positons; increased diameter gives adequate clearance for inserting a greater variety of 1" stops.
• Trouble-Free Flop Valve - pressure-seating, self-aligning, self-centering; molded neoprene gate washer; lever handle has positive lock - open or closed - with position indicator plate; "O" ring on flop valve stem eliminates packing adjustment

Reversible Power Operator with Automatic Feed

Drill and tap a 3/4" hole in three minutes, using the electric or air power operations, which are specifically designed for use with the B-100 Machine.  No adapters or conversion parts are required.  Either type of power operator attaches directly to top of boring bar and feed yoke.  After hole has been drilled, loosen wing nut to release the automatic feed driver, then continue to make tap under power.  Afer completing tap, flip the switch on the power operator to reverse direction of the motor and withdraw the tool under power.  While drilling, boring bar feed is even and completely automatic - tool is not over-crowded; does not over-heat; gives longer effective tool life.

Assured Rigidity

On the Main - Pressure tight connections start with complete machine rigidity on the main.  Aluminum alloy chain yoke has high strength - lightweight.  Chain hook washers are widely spread and deeply recessed in yoke to prevent slipping off on large diameter pipe.  Chain hook cannot rotate - chain shank on chain hook for it Square shank on chain hook fits inside square hole in chain washer.  Square shank on chain washer prevents turning in yoke. Acme threads on chain hooks give long life.  Chain hooks, Chain hook washersers and chain hook nuts are cadmium plated to resist corrosion.

In the Boring Bar - Perfect alignment of the boring bar is assured by three boring bar bearings; two, widely spaced in the feed sleeve, and the third at the extreme bottom end of the boring bar.  The lower bearing is of molded nylon and closely bears against a machined surface in the body when the drill first contacts the main and also when the stop is being inserted.  Curvature of the stop is being inserted. Curvature of the pipe cannot deflect the drill - tools are relieved of unnecessary stresses and give longer effective life.  These three widely spaced boring bar bearings assure perfect centering of tool and stop for accurate threading and a pressure-tight connection.

New Tool Retainer with Independent Drive

Drive pins in shank of new combined drill and tap or E-Z Release Screw Plug slip into notches in the boring bar socket.  All driving force is exerted aginst these drive pins, preventing damage to the structure of the pool shank.  Tool retaining screw in replaceable bronze sleeve bears against the upper part of the circular groove aound tool shank - holds tool tight in boring bar socket.  This new holding and driving arrangement assures perfect tool-boring bar alignment and maximum rigidity, for long tool life.

No problem to remove tools in the "B-100".  Just loosen the tool retaining screw, tap the knockout pin and the tool holder and the tool slifes out of your hands.
