Boring Bars

BOREMaster 8200

The DL Ricci BOREMaster 8200 is perfect for large boring applications in turbines, stern tubes, rudder posts, struts, missile silos, hinge covers, bearings, gun mounts, large earth moving equipment, valve chambers, wicket gates and seal rings. The system can be configured horizontally, vertically or inclined within a work piece and fits conveniently in limited space.

No other portable line boring system can match the BOREMaster 8200 for smooth boring, accurate alignment, easy set-up and large diameter capacities. Standard models are available to finish bores from 6" to 96" in diameter and in lengths of up to 24ft. A unique coupling arrangement is available to accommodate longer bores. The drive assembly and main bearings slide onto the boring bar and are easily fixed at any point on the bar. The boring heads are split for easy installation and removal, and the facing arm may be substituted for smooth, accurate facing operations without further modifications to the overall system.

Features & Benefits:

  • Bars available from 4" to 12" diameter
  • One-piece precision bar hardened to 50-55 Rockwell C
  • Compact electric or hydraulic drives provide constant torque and vibration-free cutting
  • 2-axis programmable position control available
  • Split-design boring head allows easy positioning anywhere on the bar
  • Self-aligning spherical roller bearings provide stable bar support

BOREMaster 2500

The DL Ricci BOREMaster 2500 is a compact and versatile portable line boring system. Despite its small size, the 2500 model is a real work horse.

The BOREMaster 2500 utilises a steel acme feed screw to feed the cutting tool along the boring bar with better stability and accuracy than less rigid push-pull boring systems. This makes it ideal for the repair of mining and quarry equipment, power generation machinery, and other rotating equipment.

Features & Benefits:

  • Rigid bar assembly reduces vibration, improves cut quality
  • 2.5” diameter bar provides stable, more accurate bores
  • Easy set-up – fewer attachments and simplified adjustments
  • Longer bores on each set-up, up to 4ft with a 6ft bar
  • Bars available in 4ft, 6ft and 8ft lengths; custom lengths available
  • Reduced mechanical stress extends life and reduces maintenance
  • Space-saving – the cutting head travels, not the bar
  • More versatile – a single motor drives bar speed from 30 to 120 rpm
  • Wide boring range, from 4” to 26”, to cover more applications

BOREMaster 1250PM

The affordable, compact and rugged design of the DL Ricci BOREMaster 1250PM is capable of repairing bores from 1.5" to 6" in diameter with unprecedented ease. At the heart of the 1250PM model is the unique automatic axial feed and micrometer-adjustable tooling. The automatic feed enables operators across the range of skill levels to machine smooth and accurate bores with precision. The axial feed assembly automatically feeds the boring bar a fixed 0.0025" per bar revolution so you never have to worry about overfeeding.

The optional micrometer-adjustable tool setter allows the depth of cut to be set to within 0.0005". Easy to use functionality is not the only strength of the BOREMaster 1250PM, it also boasts a light weight design making it highly portable.

Features & Benefits:

  • It is the lightest, most compact unit on the market
  • Performs conventional line boring and stub boring
  • Easy set-up; micrometer adjustable tooling
  • Diameters from 1.5” to 6”
  • Fixed feed rate of 0.0025” per revolution
