Product Overview
Breaker chisels – also called bits or working tools – are the replaceable front‑end tools that take the direct hit from the breaker piston and transfer that energy into the material you're breaking. They're the primary wear item on any breaker, taking repeated impact, abrasion, and bending loads, so they need to be swapped out periodically as they wear down or get damaged. Picking the right chisel type for your material and job makes a real difference in productivity and tool life – the wrong one will slow you down, wear out faster, and can even stress the breaker's internal parts. TGEC offers four main chisel types, all made from high‑strength alloy steel with proper heat treatment, to cover the full range of demolition and rock breaking work. Part of the TGEC excavator breaker working tools and spare parts lineup.
TGEC supplies breaker chisels for its side‑type, silenced box‑type, top‑type open‑body, and gas‑free R‑Series, M‑Series, and V‑Series breakers, with tool diameters from 40 mm for compact 0.5‑ton mini excavator breakers up to 255 mm for heavy‑duty 160‑ton quarry rigs. Each chisel type has a specific tip geometry and cross‑section profile optimized for particular materials and breaking actions, and the shank is precision‑machined to match the breaker's tool holder and retaining pin setup. Using a chisel with incorrect dimensions, material properties or heat treatment can lead to accelerated wear, poor fit or premature tool failure. For dealers, rental fleets, quarry operators, and mining companies, TGEC offers volume pricing, custom configurations, and fast shipping to keep downtime to a minimum.
Chisel Types and Applications
TGEC chisels come in four primary types, each with a specific tip geometry for different materials and breaking jobs.
| Chisel Type | Primary Application | Secondary Applications |
|---|---|---|
| Moil Point | General demolition and quarry work | Breaking slag, demolishing foundations, roadway drivage, mining operations |
| Blunt Tool | Crushing large rocks in quarries | Crushing slag, ground compaction, secondary breaking of oversize boulders |
| Flat Point (Wedge) | General breaking with cutting action | Digging pits in rocky subsoil, separating rock slabs, asphalt cutting |
| Conical Point | Penetrative breaking in medium‑hard materials | General demolition work where initial penetration is required |

The moil point is the most common and versatile chisel – its pointed tip concentrates impact energy on a small area, making it effective for general demolition, concrete breaking, and quarry rock. It's the default choice for most breaker work and comes standard with new breakers. The blunt tool has a wide, flat working end that spreads impact over a larger area – ideal for crushing applications like secondary quarry breaking, oversized boulder reduction, slag crushing, and ground compaction. The flat wedge has a wide blade tip that delivers a cutting action – great for asphalt cutting, rock slab separation, and digging in rocky subsoil. The conical point has a tapered tip that balances penetration and impact area – effective for medium‑hard materials and general demolition where initial penetration is needed, and it holds a functional point longer as it wears compared to a sharp moil point.
Materials and Manufacturing
TGEC chisels are forged from high‑strength alloy steel with chromium, molybdenum, nickel, and other elements for hardenability, impact toughness, and wear resistance. Precision forging aligns the grain flow with the chisel shape, giving better mechanical properties than machined‑from‑bar tools. After forging, each chisel goes through a multi‑stage heat treatment – austenitizing, quenching, and tempering – to achieve the right balance of hardness and toughness. The working tip receives additional surface hardening for maximum wear resistance, while the shank and retaining pin areas are maintained at a slightly lower hardness for better toughness and crack resistance. After heat treatment, each chisel is CNC‑machined and inspected for dimensions, hardness, and surface condition before shipment. For customers with special needs, TGEC can produce custom chisels with specific tip geometries, dimensions, materials, or surface treatments.
Chisel Selection and Replacement
Choosing the right chisel comes down to your primary material, the breaking action you need, and your breaker model. For general‑purpose demolition, concrete breaking, and rock work, the moil point is generally the most versatile choice. For quarry secondary crushing, boulder reduction, slag crushing, and ground compaction, the blunt tool is generally better suited. For asphalt cutting, rock slab separation, and cutting or splitting work, the flat wedge does the job. For medium‑hard materials where you need both penetration and decent tool life, the conical point is a solid middle ground. Not sure? The moil point is generally the most versatile choice, and our technical team can give you a specific recommendation based on your material, application, and breaker.
Replace the chisel when the tip is worn down to approximately 20–30% of its original length as a general guideline, or when cracks, bending or excessive retaining‑pin‑hole wear are present. Running a worn chisel puts extra stress on the breaker piston, front head, and bushing, which can lead to accelerated wear or damage on those expensive parts. Inspect the chisel daily as part of your routine breaker maintenance – check the tip, the pin hole, and look for cracks or bending. Swapping a chisel is a simple field job – pull the retaining pins, slide out the old one, slide in the new one, and reinstall the pins. While you're at it, check the front head bushing and retaining pins for wear too.
Fleet and Dealer Programs
For dealers, rental fleets, quarry operators, mining companies, and contractors running multiple breakers, TGEC offers fleet and dealer chisel programs with volume pricing based on annual purchasing volume, dedicated account management, and custom chisel kits tailored to specific breaker models and fleet setups. All programs are customized to your needs, breaker models, and applications, and our chisel program team works with you to develop a procurement plan that maximizes uptime and cuts total costs.
