Straight Die Grinder 1/4 in NPT Inlet

The SPEEDAIRE 12V734 is a medium-duty straight die grinder built for metalworking tasks. It connects to a compressed air supply through a 1/4 in NPT female inlet. The tool delivers 0.3 hp and reaches a maximum speed of 31,000 RPM. It is suited for operators who need a compact pneumatic grinder for steel applications.

Bare Tool With Collet And Case

The package ships as a bare tool with a 1/4 in Erickson collet installed and a protective case included. No additional accessories or lubricants are bundled. The barrel grip and mechanical brake remain the only operator controls provided. Buyers who want extra collets or a complete kit must source those items separately.

1/4 Inch Collet Capacity

The fixed 1/4 in collet size determines which shank accessories can be used directly. Users requiring larger 3/8 in or metric shanks cannot fit them without a different tool. The straight orientation and 0.3 hp rating suit light deburring and finishing rather than heavy material removal.

Questions about this item

How often will the 1/4 in Erickson collet need replacement?

The collet is included with the bare tool and should be inspected regularly for wear or run-out; replace it when gripping force drops or damage is visible.

What limits continuous operation at 31,000 RPM?

Sustained high-speed running is constrained by the 0.3 hp motor and air supply capacity; heat buildup in the barrel grip will appear first.

How hot and loud does the straight grinder get during all-day use?

The barrel grip transmits motor heat to the hand, and the mechanical brake adds noise; expect noticeable warmth and a steady high-pitched whine at full speed.
