The DongCheng HD100603 400g Machinist Hammer is built for heavy-duty metal fabrication, industrial assembly lines, and demanding mechanical maintenance. Drop-forged from premium 45# carbon steel, the 400g head delivers high striking mass and driving power for tough metalworking operations.

Heat-treated under strict standards, both the square flat striking face and the cross pein resist chipping, splitting, and mushrooming. The hammer is mounted on a 325mm high-strength two-color fiberglass handle engineered to dampen heavy impact vibrations. The ergonomic non-slip handle ensures a secure grip and maximum swing leverage in heavy workshop environments.

Key Features

• High-Mass 400g Striking Head: Delivers substantial impact force for heavy metalworking and stubborn mechanical parts.
• Drop-Forged 45# Carbon Steel: Precision heat-treated head resists fracture and surface wear under repeated heavy impacts.
• Cross Pein & Flat Face Combination: Dual-purpose profile allows flat face driving and precision peen metal stretching/forming.
• High-Strength 325mm Fiberglass Core: Effectively dampens rebound shock waves to protect user joints.
• Two-Color Non-Slip Handle: Ergonomically contoured rubberized grip provides total control and swing stability.
