Chicago Pneumatic Extended Shaft Straight Die Grinder | CP7412 | 22000 RPM | 1/4" (6 mm) Collet

Built for extended-reach straight grinding in body shop, vehicle service, and MRO applications, the Chicago Pneumatic CP7412 Extended Shaft Straight Die Grinder delivers 22,000 RPM free speed for fast deburring, cleaning, contouring, and light material removal with compatible carbide burrs and mounted abrasive accessories. Its catalog-listed 1/4" / 6.0 mm collet supports small shank-mounted tooling, while the 0.6 HP / 420 W pneumatic motor gives users more power than the 0.34 HP CP74 models for longer-reach work. The extended straight body helps reach deeper into brackets, seams, recessed edges, fixture areas, and repair spaces where a short straight grinder may not provide enough access.

The CP7412 is part of Chicago Pneumatic's CP74 die grinder series, a body shop and MRO range built with different head styles for different access needs. Compared with the CP7410, this model runs at a lower 22,000 RPM speed but uses the higher-output CP74 motor platform, giving technicians a useful balance of reach, control, and power. A spindle lock system allows carbide burr changes with one wrench, while the rear exhaust directs spent air away from the work area during repeated grinding, cleanup, and finishing tasks.

• 0.6 HP / 420 W motor provides more output than lower-power CP74 models for longer-reach grinding and cleanup tasks.
• Spindle lock system allows carbide burr changes with only one wrench, helping reduce accessory-change time between operations.
• Catalog-listed 1/4" / 6.0 mm collet capacity supports compatible small shank-mounted abrasive accessories and carbide burrs.
• Rear exhaust helps direct spent air away from the workpiece and the operator's immediate line of sight.
• Composite housing helps reduce heat transfer between the motor and sleeve during repeated use.
• Safety lever starting system helps reduce accidental start risk during handling, setup, and daily operation.

Applications:

• Body shop repair: deburring panels, cleaning seam areas, smoothing brackets, and reaching into tight vehicle body sections.
• Vehicle service: grinding and cleanup around mounts, tabs, exhaust brackets, frame details, and fabricated repair components.
• Industrial maintenance and MRO: light edge cleanup, burr removal, and surface preparation on guards, covers, brackets, and small machine parts.
• Metal fabrication: contouring small parts, cleaning drilled holes, removing minor burrs, and preparing edges before assembly or finishing.
• Workshop and garage use: extended-reach air grinding for users who need straight-line access and have a properly sized compressed-air supply.

FAQs:

• Q: What is the CP7412 best used for?
  A: The CP7412 is used for extended-reach straight grinding, deburring, cleaning, and light finishing with compatible mounted accessories. Its long body helps reach deeper into seams, brackets, recessed edges, and repair spaces than shorter straight die grinders.
• Q: How is the CP7412 different from the CP7410?
  A: Both models are long straight die grinders in the CP74 series, but the CP7412 runs at 22,000 RPM and uses a higher-output 0.6 HP / 420 W motor. The CP7410 runs at 27,000 RPM with lower listed power, making it the faster but less powerful long-straight option.
• Q: What does the spindle lock do?
  A: The spindle lock holds the spindle during accessory changes. This lets the operator change carbide burrs with one wrench instead of using a two-wrench setup.
• Q: What air supply does this grinder require?
  A: Chicago Pneumatic lists 3.0 CFM / 1.4 l/s air consumption at load and 3.6 CFM / 1.7 l/s at free speed. Use clean, regulated air at 90 PSI / 6.3 bar through the recommended 0.38" / 10 mm minimum hose diameter.
• Q: Can this grinder use any burr or mounted abrasive?
  A: No. The accessory must match the installed collet size and must have a maximum operating speed equal to or higher than the grinder's 22,000 RPM free speed. Always confirm shank size, accessory type, workpiece material, and the accessory manufacturer's safety rating before use.
