42CrMo Rock Breaker Chisel Four Side Forged Hydraulic Hammer Chisel for Eddie 195
This four-side forged chisel is specially customized for EDDIE195 hydraulic rock breaker, manufactured from premium 42CrMo chrome-moly alloy steel. Full four-side hydraulic forging plus staged quenching & tempering and tip high-frequency heat treatment deliver balanced hardness and toughness. Ideal OEM replacement spare part for EDDIE195 hammer, matched with 35–45 ton excavators for heavy-duty applications including granite quarrying, hard rock mining and reinforced concrete demolition. Dense internal metal structure from four-side forging effectively avoids premature breakage, head peeling and fast abrasion of ordinary rolled chisels with 2~3 times longer service life.
1,Raw Material
Grade 42CrMo alloy structural steel, mainstream premium raw material for heavy breaker chisels. Optimized Cr-Mo composition features excellent hardenability, fatigue resistance and impact resistance, tensile strength ≥1080MPa, stable toughness under low-temperature mining environment.
2,Four-Side Full Forging
Full four-direction hydraulic forging upsets raw steel to eliminate internal cavities and refine metal grain. Different from lathe-processed round steel chisels, forged structure owns wear-resistant outer layer & tough core, anti-bending and anti-cracking under continuous heavy hitting, 40% higher wear resistance on abrasive hard rock sites.
3,Heat Treatment
Graded differential heat treatment: striking end HRC44~48 for anti-peeling; working tip HRC55~58 for superior abrasion resistance; main body tempered to HRC38~42, balanced hardness & toughness to avoid tip breakage or shaft fracture.
Q1: Why choose 42CrMo four-side forged chisel for Eddie 195 breaker?
A1: Eddie 195 hydraulic breaker is a large high-power mining hammer with high impact force. Ordinary chisels are easy to break and wear quickly. This 42CrMo rock breaker chisel adopts four-side forging process with dense internal structure, high hardness and strong toughness, perfectly matching the heavy-load working demand of Eddie 195 breaker, with longer service life and higher construction efficiency.
Q2: What is the difference between forged chisel and ordinary rolled chisel?
A2: The four-side forged hammer chisel has denser metal texture, no internal pores, uniform stress bearing, and is not easy to break suddenly. Ordinary rolled chisels have loose internal structure, prone to crack and fracture under long-term high impact. Forged chisels have 2-3 times longer service life and better wear resistance.
Q3: Is the chisel easy to collapse or bend when breaking hard rock?
A3: No. Made of high-toughness 42CrMo alloy steel and processed by overall heat treatment, this extra wear-resistant hammer chisel balances hardness and toughness. It effectively resists tip collapsing and rod bending during hard rock and granite breaking, adapting to harsh mining working conditions.
