Grobet 31.609 Swiss-pattern Slitting File Cut 4 Needle

Product Description

The GROBET 31.609 is a Swiss-pattern slitting file designed for precision filing work in tight grooves, slots, and narrow channels. With an overall length of 6.25 inches and a cut length of 3 inches, this needle-grade file delivers fine, controlled material removal. The Cut 4 designation places it in the smooth end of the Swiss-pattern cut scale, making it suited for finish work and detail deburring. The tang-style end accepts compatible file handles for secure grip during use. It is sold individually without a handle attached.

This slitting file is intended for trade and toolroom applications where narrow-profile access is required. The 0.2 inch width and 0.11 inch thickness allow it to enter slots and kerfs that wider files cannot reach. Machinists, toolmakers, jewelers, and precision fabricators commonly use slitting files for fine notching, slot widening, and saw-tooth dressing. It is equally useful in maintenance and repair work where tight-clearance filing is needed on metal components.

Installation Notes

A licensed machinist, toolmaker, or skilled tradesperson should select the appropriate handle before use, as operating a tang file without a handle presents a puncture hazard. Secure a properly sized handle rated for needle files before applying pressure. Keep the file clean of filings using a file card or brush to maintain cut efficiency and prevent loading. Store separately from other tools to protect the precision-cut teeth from damage.
