Bosch HS1472 10" SDS-Plus® Bulldog™ Xtreme Star-Point Twist Demolition Hammer Chisel Bit

The Bosch HS1472 10-inch SDS-plus® Bulldog™ Xtreme star-point twist demolition hammer chisel bit fractures poured concrete slabs, mortar beds, tile thinset, and structural masonry walls with rapid material clearing. Engineered with a helical star-point twist head profile that actively clears fractured aggregate and dust away from the tip, this specialized chipping accessory produces a 15 percent higher material removal rate than traditional straight points while preventing tool binding inside tight relief cracks. Outfitted with inductively hardened drop-forged alloy steel that self-sharpens as it erodes, an overall 10-inch tool reach, and a universal SDS-plus slotted drive shank, it equips commercial tile contractors, remodeling specialists, and electrical installers with continuous non-jamming demolition across corded and cordless rotary chipping hammers.

Best Used For:

  • Tile Thinset and Mortar Bed Scaling: Chipping away hardened floor thinset, mortar beds, and ceramic tile underlayment cleanly without gouging subfloor substrates.
  • Interior Masonry and Concrete Trenching: Chiseling conduit chases, electrical box cutouts, and plumbing pipe relief tracks into structural poured concrete and CMU block.
  • Targeted Concrete Edge Fracturing: Breaking down expansion joint edges, decorative slab borders, and excess formwork concrete flashing with pinpoint impact accuracy.

Key Performance & Safety Features

  • Star-Point Twist Head Profile: Helical twisting ridges channel fracturing forces across an expanded contact area, increasing breakout speed while rejecting pulverized dust.
  • Continuous Self-Sharpening Architecture: Engineered cutting geometry retains its sharp penetrating apex throughout tool life to eliminate manual resharpening downtime.
  • 15% Higher Removal Efficiency: Dynamic debris-ejecting twist flutes reduce friction to channel maximum kinetic impact energy into breaking concrete faster.
  • Anti-Jamming Engineering: Angular relief facets prevent the bit from pinching or locking up when driven deep into structural aggregate stress cracks.
  • Inductive Hardening Treatment: Advanced thermal metallurgical processing reinforces the alloy steel core to resist twisting, bending, and shank fatigue.
  • Universal SDS-Plus Fitment: Standardized slotted drive connection seats solidly into all commercial SDS-plus rotary hammer drills and dedicated demolition hammers.
