Needles for Needle Scalers

CS Unitec's Trelawny™ needles last 10x longer than standard needles. Save time and money with fewer needle changes and less downtime.

All of CS Unitec's Needle Scalers are delivered from stock complete with 180mm long x 3mm diameter chisel tipped high performance needles. Other needle holders are available as accessories for use with 2mm and 4mm diameter needles. We also offer spark resistant needles for use in potentially hazardous areas and Ex zones, as well as stainless steel needles for use in humid areas - such as applications in the food processing industry - where corrosion is a concern.

Standard pack set is one carton of 6 sets. Some models are packed as an individual set in a box. Boxes of 100 qty. needles in a durable, reusable plastic container are available, as well as larger quantities.

Chisel Tip
These needles will clean the same materials as a pointed tip, but will leave light surface marking.

Flat Tip
Flat-tipped needles will reduce marking on metal surfaces and can give a polishing effect. For use on thin-gauge metals and any surface where a light treatment is required.

2mm needles used on a welded joint produce a similar effect to shot peening, reducing stress in the weld.

Pointed Tip
Sharpened to a conical point, these are the most effective in breaking through very hard scale on materials where some surface indentation is permissible, or where a roughening or keying of the surface is desirable.
