Split Frame Clamshell 1 – 48″

H&S TOOL’s new split-frame clamshells are essentially portable lathes. Offering the versatility to cut and bevel (simultaneously if required), face, counterbore, and o/d machine pipes (and vessels) of almost any diameter. A lightweight aluminium body encases a steel inner ring gear running on solid bearings, ensuring manageability, yet extreme strength and durability. It enables rapid, repeatable concentric setup, even on out-of-round pipes and joints, coupled with wide, hardened clamping feet and easy-to-read rule marks. A range of tooling, power units, and accessories allows you to tailor your machine to your particular job.

Product Advantages

• Advanced Cam Roller Bearing System
  Ensures fine adjustment for optimal performance and smooth, precise rotation, reducing maintenance requirements and extending machine life.

• Heavy-Duty Split Frames
  Manufactured from high-grade aluminium and treated steel crown, engineered for demanding industrial on-site applications.

• Quick Lock/Unlock Splitting Hinge
  Enables rapid setup directly on pipes in situ, saving valuable installation time.

• Protective Custom Case
  Supplied in a custom-made metal box with precision foam insert for maximum machine protection (up to HSSFC48).

• Advanced Feeding System
  Worm and crown mechanism evenly distributes pressure across the feeding screw, minimizing vibration and tool wear for cleaner, longer-lasting cuts.

• Two-Bolt Motor Mount System
  Allows fast motor installation with universal drive block compatibility. Machines from 16″ upwards feature dual mounts, with optional front drive motor mounting.

• Modular Block Jaws
  Movable locking system with reinforced external metal plate to relieve stress on the aluminium ring. Compact clamping foot (40 × 60 mm / 1.57 × 2.36″) ensures reliable grip.

• Telescopic Jaws
  Enlarged clamping foot (55 × 115 mm / 2.16 × 4.52″) and external mounting provide greater strength and accuracy, ensuring rapid setup and stability.

• Double Striker Feed
  Delivers 0.2 mm (0.008″) per revolution, combined with extended engaging handle for hands-free operation.

• Comprehensive Tool Boxes & Accessories
  Configurable tool boxes designed to accommodate the full range of H&S tooling.

• Counter Bore Tool Slide
  Installs directly after cutting to eliminate internal inconsistencies before welding. Adjustable 0–45° with 150 mm (6″) feed. Optional internal bevel extension offers 20 mm (0.79″) feed for orbital welding prep.

• Outside Bevel Tool Slide
  Removes external coatings or reduces pipe OD. Robust 300 mm (11.8″) module with 250 mm (9.85″) functional feed, customized per application.

• Swivel Locking Jaws
  Enable pipe offset positioning (1–5° inclination), ideal for elbows, conical surfaces, and offset cuts.

• Flexible Power Options
  Available in servo electric, hydraulic, pneumatic, and electric drives. Mounting flanges offered in straight, elbow/right angle, or optional front-drive versions.

• NC Servo Drive Motor System

  • Single Servo System (from HSSCF6): Delta 1.5 kW servo motor with wired remote, for wall thickness up to 25 mm.

  • Double Servo System (from HSSCF16): Two Delta 1.5 kW motors with touchscreen NC control and wireless remote, for >25 mm wall thickness, larger diameters, and exotic materials.
    Provides consistent torque under load with superior speed, precision, and safety.

• Precision Tooling Options

  • Formed/Solid HSS-Co tooling: For severing, beveling, double-bevel, compound bevel, J-prep, and counterbore.

  • Holder & Insert tooling: Recommended for efficiency—shared inserts reduce consumable costs.

  • Custom Tooling: Designed to match specialized applications and materials.
