Hydraulic excavators are incredibly versatile equipment that may be used for everything from grading to massive excavation to demoliton work. A bucket is the primary work tool of a hydraulic excavator, although these machines can also be outfitted with hydraulic couplers to pick up a variety of tools.
It is vital to balance your targeted productivity/penetration with the wear life of your equipment. Excessive wear can limit productivity and increase fuel consumption. Cat hydraulic excavator buckets and GET are engineered to work together to maximize life while minimizing drag.
You don't have to be an expert to choose the proper bucket tips, despite the fact that they come in a variety of forms and sizes. You can use the data below to determine whether the material you're digging in is high, medium, or low in terms of impact and abrasion, and then find the right balance of these three factors:
The ability to withstand digging and penetrating shocks and high breakout forces
The ability to penetrate tough material when it’s tightly compacted, rocky or frozen
The ability to withstand wearing, scouring and abrasive action of the material being handled
IMPCAT (material size) | ABRASION (tip life) | |||
SMALL HEX (311-319) | MEDIUM HEX (320-329) | LARGE HEX (336-390) | ||
LOW |  0 - 25 mm |  0 - 75 mm |  0 -150 mm | > 1,000 hours |
MEDIUM | 25 - 75 mm | 75 - 200 mm |  150 - 300 mm | 250 - 1,000 hours |
HIGH | 75 mm+ | 200 mm+ |  300 mm+ | < 250 hours |
BUILT TO DELIVER MAXIMUM PRODUCTIVITY AND THE LOWEST BUCKET LIFECYCLE COST IN THE TOUGHEST APPLICATIONS.
Cat Advansys is built for machine productivity, balancing tip wear material and penetration requirements. Integrated hammerless retention ensures you are back to work in minutes without a separate retainer.
Wider top surface reduces drag on the tip and adapter side as the tip moves through the material. Reduced side drag results in less force required to move the hex bucket through the material.
Adapter design directs material flow over adapter strap, which can extend adapter service life and bucket lifecycle.
Hammerless system. A 3/4 inch retainer lock requires no special tools for installation and removal.

EXCELLENT PENETRATION THROUGH VERTICAL RETENTION AND COMPACT PROFILE.
K Series delivers digging performance throughout the life of the tip with its elliptical adapter nose and vertical retention design. The twist-on fit of the tip and adapter makes installation easier.
Low-profile shape provides optimal sharpness, penetration, and digging ability throughout the tip life.
One-piece vertical retainer allows for easy installation and removal.
Rails on both sides of the adapter and a twist-on design hold the tip in place, allowing for quicker installation.

SIDE-PIN SECURITY WHEN YOUR APPLICATION DEMANDS IT.
Great performance and proven reliability over time—that’s what you get with this classic horizontal retention system, a staple in the construction and mining industries.
BOOST YOUR VERSATILITYIndustry-standard side-pinned design performs across a variety of applications. ENHANCE YOUR RELIABILITYWeld-on adapters offer excellent retention. IMPROVE SAFETY & MAINTENANCE TIMEAbility to retrofit means you can use the hammerless CapSure™ system. | J SERIES TIP OPTIONS:
|
General Duty tips offer a reliable, competitively priced parts option for small to medium-sized excavators operating in low to medium impact conditions. Tips are available in the J250-J460 size range.
General Duty tips are:
LOSE THE HAMMER, NOT THE FLEXIBILITY.
Simplify bucket tip replacement with hammerless CapSure retention. These tips are matched to side-pin adapters, allowing the flexibility to use our conventional pin retention if your application demands it.
Side-pin retrofit design used on J-style adapters means the pin is reusable.
A ¾-inch retainer lock requires no special tools and allows for hammerless installation and removal.
Positive stop is cast into the tip to prevent over-rotation—just turn 180 degrees to lock or unlock.
Tip and retainer are one system, so there’s no special assembly or extra pieces.
FASTEST INSTALLATION TIMES IN THE INDUSTRY.
Cat base edge systems go through a series of carefully controlled manufacturing processes to deliver maximum strength, durability and long life. They come completely welded and assembled, dramatically shortening your installation and replacement time.
A consistent heat-treat process maximizes strength and resists abrasion. Shot blasting removes impurities that can cause inclusions on a weld, and controlled cooling reduces the chance of stress points.
Butterbead is applied to the back side of the base edge and the top strap of the corner adapter, so you can weld the edge onto the bucket without preheating.
Base edges are designed by Caterpillar engineers for optimal performance on specific machines.
Base edge replacement involves replacing a base edge assembly, which includes adapters welded in from the factory, or replacing a bolt-on cutting edge (BOCE) base edge, which comes with factory-drilled holes for bolt-on G.E.T. Choose from three shapes (base edge for BOCE, straight and spade base edge assemblies) to get the right protection for your application.

PROTECT YOUR CORNERS - WITHOUT CUTTING THEM.
Reduce base edge end wear and subsequent corner adapter weld erosion with our BEEP design. It makes adapter replacement on the edge much easier when it’s time to rebuild the base edge assembly. BEEPs are available in a wide array of thicknesses and angles to fit 336-390 hydraulic excavators.
Through-hardened Rc ~45 (Br ~3.0) weldable steel is easily installed in the shop or the field.
Extended base edge end protects adapter corner welds.
Height and bevel are matched to the base edge, so there’s no additional fabrication.
MAINTAIN YOUR PERFORMANCE EDGE.
Protect your bucket’s structural integrity with sidebar protectors and shear blocks or increase penetration and performance with side cutters.
Protect your bucket’s structural integrity with sidebars and shear blocks.
INCREASE YOUR UPTIME
Shear block protects the pin from extreme loads and breakage, helping ensure sidebar protector retention.
CUT YOUR MAINTENANCE COSTS
Sidebar protector protects the bucket edge.
Improve your bucket’s performance while protecting your sidebars.
AVAILABLE SIDECUTTERS:
Protect your investment in buckets and base edges with these flexible components. Half arrows allow for a smooth transition of material over the base edge to protect the leading edge. Top covers complement the half arrows to protect the base edge fully. Modular edge shrouds are designed to fit any bucket configuration and extend the life of your excavator bucket edge assembly.
Individual pieces that protect the edge can be changed independently.
Half arrows cover the leading edge for smooth material transition.
Top cover reduces wear on weld joints.
