Bosch Demolition Chisel HS1926 SDS-Max Shank 16 Inch Clay Spade Tool (5-3/8 Width Blade Forged Alloy Steel Hard Soil Gravel Trench Excavation)

Bosch HS1926 16" SDS-Max 5-3/8" Wide Blade Clay Spade Chisel Bit

The Bosch HS1926 16-inch SDS-Max clay spade chisel excavates hard-packed clay soils, cuts irrigation and utility trenches, digs landscape planting beds, and loosens densely compacted gravel beds without requiring manual pickaxe labor. Manufactured in Italy from drop-forged high-strength alloy tool steel with a proprietary heat-treatment process, this 4.21-pound earth-digging bit features an extra-wide 5-3/8-inch curved scooped blade that displaces maximum material volume per hammer impact stroke. Outfitted with a standardized 16-inch overall length for extended reach and ergonomic leverage, alongside an industry-standard SDS-Max slotted shank compatible with competitive TE-Y and TE-FY hammer chucks, it equips civil utility crews, landscape contractors, plumbers, and foundation excavators with high-efficiency ground penetration across all SDS-Max rotary hammers and demolition chipping guns set to hammer-only mode.

Best Used For:

• Utility Trenching and Conduit Laying: Slicing narrow, flat-bottomed trench channels through dense clay, root-laced dirt, and hard dirt to route electrical conduit, drainage lines, and water pipes.
• Dense Earth and Hard-Packed Soil Digging: Fracturing heavily consolidated earth, caliche layers, and sun-baked soils around building perimeters and foundation footings.
• Compacted Gravel and Road Base Loosening: Pervasively breaking up tightly packed stone base, decomposed granite, and subgrade backfill prior to manual shoveling or grading.

Key Performance & Safety Features

• Extra-Wide 5-3/8-Inch Scooped Blade: Expansive curved spade geometry scoops and shears large earth volumes rapidly, significantly reducing trenching time.
• Proprietary Induction Heat Treatment: Specialized metallurgical tempering process maximizes tensile strength and fatigue resistance under continuous high-impact pounding.
• Extended 16-Inch Working Length: Provides deep trench reach and optimal ground leverage, reducing operator back strain and physical fatigue.
• Universal SDS-Max Drive Interface: Precision-machined slotted shank fits all standard SDS-Max combination hammers, dedicated chipping guns, and compatible TE-Y/TE-FY tools.
• Drop-Forged High-Strength Alloy Steel: Monolithic forged construction resists neck bending and blade chipping when encountering hidden stones and dense earth layers.
• Dedicated Earth-Digging Geometry: Specifically engineered for soils, clay, and gravel to deliver faster excavation than narrow point or flat demolition chisels.

Technical Specifications

Pro-Tip: To avoid damaging the bit or hammer mechanism, ensure the tool is used exclusively for earth materials such as clay, soil, and gravel; avoid prying against structural concrete or solid asphalt, and lubricate the SDS-Max shank with chisel grease before inserting into the chuck.
