Simonds 83501000 Rnd. Handle Needle File 5-1/2inL tool storage

Precision Swiss-Pattern Needle File

The Simonds 83501000 is a 5-1/2 inch round needle file designed for metalworkers, jewellers and model makers who need controlled material removal in tight spaces. Its Swiss-pattern construction and smooth single-cut faces suit aluminium, brass, bronze, steel and tin. The rigid tapered body reaches into small radii without flexing. Packaged in a protective box for workshop storage.

Smooth-Cut Coarseness Defines Finish

The file carries a smooth-cut rating (Finish Number 0) on four single-cut edges, which determines whether the surface left behind meets final-finish requirements or needs further polishing. Coarser or bastard cuts would remove stock faster but leave visible scoring; this grade is chosen when the next step is inspection rather than another file.

Consistent Action Under Repetitive Strokes

The natural-finish steel retains its tooth geometry during extended hand-filing sessions, so the cut rate stays predictable from the first stroke to the last. Rigid 1/16 inch thickness prevents the blade from springing away from curved workpieces, keeping contact even when pressure is sustained. No lubrication or cooling is required for the listed metals.
