Cleco 250PHF406 Pistol Grip High Torque Pneumatic Pulse Tool | Non Shut-Off | 4,000 RPM | 118 - 185 (ft-lbs) Torque Range | 3/4" Square Drive

Built for high-torque assembly stations where fast rundown and lower reaction force are both important, the Cleco 250PHF406 pistol grip pneumatic pulse tool delivers a 118 - 185 ft-lbs torque range for larger fasteners used in machinery assembly, production repair, and industrial MRO. Its hydraulic pulse mechanism (a sealed pulse unit that applies torque in short hydraulic impulses instead of continuous twisting force) helps reduce kickback at the operator’s hand compared with conventional impact-style fastening. The 3/4" square drive accepts compatible impact-rated sockets, while the 4,000 RPM free speed supports quick rundown before final pulsing.

As part of Cleco’s C Series high torque non-shut-off pulse tool lineup, the 250PHF406 sits between the 160PH456 and 400PHF356 for buyers who need more output than the 74 - 118 ft-lbs model without stepping up to the 185 - 295 ft-lbs range. The 8.6 lb tool weight, 3/8" NPT air inlet, 1/2" minimum hose I.D., and 40.6 SCFM air consumption make it best suited to production environments with a properly sized compressed air system.

Type: Pneumatic Pulse Tool | Brand: Cleco | Model: 250PHF406 | Series: C Series | Configuration: Pistol Grip | Drive Type: 3/4" Square Drive | Torque Range: 118 - 185 ft-lbs | Torque Range: 160 - 250 Nm | Free Speed: 4,000 RPM | Weight: 8.6 lb | Air Inlet: 3/8" NPT | Minimum Hose I.D.: 1/2" | Air Consumption: 40.6 SCFM

Features:

• Hydraulic pulse fastening helps control reaction force during repeated high-torque assembly work.
• Non-shut-off operation allows the operator to control the fastening cycle manually when automatic shut-off is not required.
• 3/4" square drive supports compatible impact-rated sockets for larger bolts and nuts.
• 4,000 RPM free speed helps reduce rundown time before the pulse unit reaches working torque.
• Efficient air motor supports high-torque output in production fastening environments.
• External speed control allows tool speed adjustment to suit the joint and application.
• Oilless blades and reversible operation support practical use across assembly, rework, and service tasks.
• Low maintenance construction helps reduce downtime in repeated fastening operations.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator FRL)

Applications:

• Industrial assembly: Fastening larger bolts on machinery frames, fixtures, guards, and production-built equipment.
• Heavy equipment manufacturing: Running down fasteners on brackets, mounts, housings, and fabricated subassemblies.
• Plant maintenance and MRO: Repeated bolt-up work on conveyors, pumps, skids, and machinery components where reduced reaction is helpful.
• Fleet and truck service facilities: Controlled fastening on larger service components when the air system and torque process are suitable for pulse tools.
• Production repair and rework stations: High-torque fastening where technicians need manual control of the pulse cycle instead of automatic shut-off.

FAQs:

• Q: What does "non shut-off" mean on the Cleco 250PHF406?
  A: Non-shut-off means the tool does not automatically stop when a preset torque is reached. The operator controls the fastening cycle and should use the shop’s approved torque verification process when final torque documentation is required.
• Q: How much air does the 250PHF406 require?
  A: This model is listed with 40.6 SCFM air consumption, a 3/8" NPT air inlet, and a 1/2" minimum hose I.D. It should be paired with an air supply that can maintain adequate flow during repeated production cycles.
• Q: What is the difference between this model and the Cleco 160PH456?
  A: The 250PHF406 provides a higher 118 - 185 ft-lbs torque range compared with the 160PH456, which is rated at 74 - 118 ft-lbs. Choose the 250PHF406 when the application requires more fastening torque while staying in the same 3/4" square drive C Series non-shut-off family.
• Q: Can this tool be used with regular Chrome sockets?
  A: No. Use properly sized 3/4" drive impact-rated sockets with pneumatic pulse tools. Standard hand sockets are not intended for powered fastening tools.
• Q: Is this tool intended for home garage use?
  A: This is a high-torque industrial pneumatic pulse tool with significant air demand. Most home garages will not have the compressor capacity or torque-control process needed to use it effectively.
