3M 7100230888 | 3/8" Diameter x 1" Width SR Cutter

Description

The 3M 7100230888 is the 3M SR Cutter designed for efficient, non abrasive removal of sealants and coatings in aerospace and industrial maintenance. The plastic rotary cutter uses durable cylindrical blades and a ¼ inch -28 male threaded metal mandrel to attach to right angle drills, replacing manual scraping and solvent cleaning. The SR Cutter removes polysulfide, polyurethane, RTV and silicone sealants quickly while minimising damage to primers, paint and substrate. Available in cutter styles for fillet seals and fastener heads, the tool improves productivity and reduces rework in repair and teardown workflows. Use this 3m sr cutter where fast, controlled sealant removal is required without chemical solvents.

Product Features and Benefits

Non abrasive plastic blades for substrate protection

The 3m sr cutter has cylindrical plastic cutters that remove sealant with minimal abrasion to paint, primer or metal, reducing follow-up repair or repainting. Blades remain effective without resharpening.

1/4"-28 metal mandrel for right-angle drills

Robust metal mandrel provides secure mounting to right angle power tools for controlled low speed operation and repeatable performance on aircraft and structural assemblies.

Two cutter styles for fillets and fastener heads

No. 3 cutter (0.4" Ø) fits between rivets and into tight spaces; No. 8 cutter (≈1" Ø) fits over fastener heads for thorough removal around protrusions.

Replaces manual scraping and chemical solvents

Speeds sealant removal operations, eliminates solvent handling and waste, and reduces operator fatigue compared with manual scraping tools.
