Flat Tip Needles

The flat tip needles will reduce marking on metal surfaces and can actually give a polishing finish.
For use on thin gauge metals and any surface where light treatment is required.
2mm needle used on a welding joint produces a similar effect to shot peening, reducing stress in the weld.

Pointed Tip Needles

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 actually desirable

Stainless Steel Needles

Available in 3mm flat tip form only, to be used in applications such as refurbishment of food processing machinery or areas of high humidity where the corrosive effect on needles would be prohibitive. Used on decorative concrete surfaces where contamination of the surface from carbon steel needles is undesirable.
