Accupro 784886 ER16 Collet 0.281 Inch

Product Description

The ACCUPRO 784886 is an ER16 series collet designed for use in CNC machining centers, milling machines, and high-speed spindles that accept the ER16 collet standard. This collet holds tool shanks at a decimal inch size of 0.281 inches, with a minimum collet capacity of 0.25 inches, providing a secure clamping range suited to small-diameter cutting tools. Measuring 1.9 inches in height and 1.2 inches in diameter, the 784886 is compact and lightweight at 0.05 pounds. It is installed by machinists, toolroom technicians, and CNC operators working in precision metalworking environments.

The ACCUPRO 784886 is suited for applications requiring accurate tool holding in light-duty to medium-duty cutting operations. The ER16 collet series is widely used in high-speed spindle applications, benchtop CNC mills, and toolroom milling machines. The 0.281-inch capacity accommodates specific tool shank sizes common in die work, engraving, and small-part machining. This collet is sold individually and is appropriate for shops stocking single-unit replacements or supplementing an existing ER16 collet set.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. Ensure the spindle or collet chuck is fully de-energized and at a complete stop before removing or seating the collet. Clean the collet taper and chuck bore thoroughly before installation to prevent runout caused by chips or debris. Do not exceed the collet clamping range stated by the chuck manufacturer.
