Bosch Demolition Hammer Chisel HS1490 SDS Plus Shank Bulldog Bit (5-3/4 Inch Overall Length Carbide Tip Stubby Point Mortar Joint Brick Tuckpointing)

Bosch HS1490 5-3/4" SDS-Plus® Bulldog™ Carbide-Tipped Stubby Point Chisel Bit

The Bosch HS1490 5-3/4-inch SDS-plus® Bulldog™ carbide-tipped stubby point demolition hammer chisel bit extracts hardened mortar joints, tile setting beds, thick exterior plaster, and crumbling grout lines during delicate structural brick repointing. Engineered with an ultra-durable tungsten carbide-tipped point brazed into a compact drop-forged alloy steel body, this specialized masonry restoration accessory channels concentrated impact energy to fracture mortar bonds cleanly without fracturing surrounding historic clay bricks. Outfitted with a stubby 5-3/4-inch profile for tight-clearance control, proprietary inductive heat treatment to resist shank fatigue, and a universal SDS-plus slotted drive interface, it equips professional tuckpointers, restoration masons, and commercial bricklayers with precise, high-speed joint clearing across corded and cordless rotary chipping hammers.

Best Used For:

• Historic Brick Repointing and Tuckpointing: Chipping and clearing out weathered mortar joints, lime-based setting beds, and hard masonry cement without blowing out surrounding brick edges.
• Close-Quarter Masonry and Plaster Chiseling: Scraping localized stucco coats, internal wall plaster, and excess concrete formwork seams inside narrow staging reveals and light wells.
• Precision Grout Joint Raking: Removing deteriorating structural grout lines between natural stone veneer, clay pavers, and decorative concrete blocks.

Key Performance & Safety Features

• Tungsten Carbide-Tipped Inset: Industrial carbide point retains razor-sharp cutting edges under continuous impact, resisting rapid edge rounding in abrasive mortar.
• High-Impact Stubby Geometry: Short 5-3/4-inch body minimizes deflection and focuses direct hammer kinetic stroke energy for close-range guidance.
• Proprietary Heat-Treatment Matrix: Advanced metallurgical thermal hardening reinforces the high-tensile alloy steel core to absorb repetitive mechanical shock without snapping.
• Precision Slotted SDS-Plus Shank: Universal slotted drive configuration seats securely into all commercial SDS-plus rotary hammers for positive power transfer.
• Non-Destructive Joint Cleaving: Sharp carbide tip fractures brittle mortar beds cleanly to prevent impact shock from splitting adjacent architectural brick units.
• Hammer-Only Mode Optimization: Purpose-engineered for smooth, linear percussive chipping in rotation-stop hammer applications.

Technical Specifications

Pro-Tip: Align the carbide tip parallel within the center of the bed joint and let the rotary hammer's percussive impact fracture the mortar; guiding the bit at a shallow angle prevents the carbide corners from nicking or spalling the delicate faces of historic brickwork.
