Abrasive flap disc PSG Star Flex STAL T29 125×22 mm grain 60 TLS1252260

The PSG Star Flex STAL T29 flap disc TLS1252260 is a 125×22 mm abrasive disc with 60 grit designed for angle grinders. Engineered for work on steel and similar metals, the disc features layered abrasive flaps that provide consistent material removal, controlled stock removal and uniform surface preparation. Its 22 mm bore fits standard 125 mm angle grinders and the T29 curved shape helps maintain contact geometry for blending welds, deburring and edge finishing.

Advantages

This flap disc combines a 60-grit abrasive for efficient stock removal with a layered flap design that wears evenly, extending usable life and keeping cutting action consistent. The curved T29 profile improves contact control on curved and flat surfaces, while the 125 mm diameter provides a balance between reach and maneuverability. The construction reduces vibration and helps achieve smoother transitions when blending welds or finishing edges on steel components.

Suitable for

• Grinding and blending weld seams on steel
• Deburring cut edges and removing burrs
• Surface preparation before painting or coating
• Edge finishing and light shaping of metal parts

When it may not be suitable

This flap disc is intended for work on steel and similar metals; it is not optimized for stainless steel where specific abrasives or lower aggressiveness may be preferred to avoid contamination and heat discoloration. For heavy stock removal on very thick material or for concrete and masonry work, more aggressive or purpose-built discs would be more suitable.

Key specifications

• Disc diameter: 125 mm
• Bore diameter: 22 mm
• Abrasive grit: 60
• Shape/profile: T29 (curved flap)
• Material application: steel and similar metals

How to use

Mount the flap disc on a compatible 125 mm angle grinder with a 22 mm arbor, ensuring the grinder is unplugged or battery removed during installation. Operate the grinder at the manufacturer’s recommended speed and apply even, controlled pressure—allow the abrasive flaps to do the cutting rather than forcing the disc into the workpiece. Move the disc smoothly across welds or edges to blend and finish; avoid excessive dwell in one spot to reduce heat build-up and prevent gouging. Replace the disc when flaps are worn down to the backing layer or performance declines.

What to consider before purchase

• Match disc diameter and bore to your angle grinder (125 mm / 22 mm)
• Choose grit 60 for a balance of stock removal and surface finish
• Confirm compatibility of T29 curved profile with intended tasks (blending, edge finishing)
• Ensure the disc is suitable for the specific metal type you will work on

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Allow the flap disc to rotate up to speed before contacting the workpiece, and work at moderate angles for blending and finishing to maintain control and extend disc life.
