Cat Hydraulic Excavators are the most versatile machines on the jobsite, ranging from small landscaping projects to large surface extraction mines—and everywhere in between.
SYSTEM OVERVIEW
Hydraulic excavators are extremely versatile machines used for a variety of purposes, from grading to mass excavation to demolition work. A hydraulic excavator's main work tool is a bucket, but these machines can also be equipped with hydraulic couplers to pick up a variety of tools.
Balancing your desired productivity/penetration with the wear life of your system is critical. Excessive wear material can reduce productivity and increase fuel burn. Cat hydraulic excavator buckets and G.E.T. are designed as a balanced system to increase life while minimizing drag.
TIP SELECTION GUIDE
Even though bucket tips come in many shapes and sizes, you don't have to be an expert to choose the right ones. Use the chart below to determine if the material you're digging in is high, medium or low impact and abrasion—then find the balance you need among these three factors:| Description |
|---|
| 1. STRENGTH The ability to withstand digging and penetrating shocks and high breakout forces. |
| 2. PENETRATION The ability to penetrate tough material when it's tightly compacted, rocky or frozen. |
| 3. WEAR LIFE The ability to withstand wearing, scouring and abrasive action of the material being handled. |
K SERIES TIP & ADAPTER SYSTEM
MAXIMUM PRODUCTIVITY MEETS HAMMERLESS RETENTION.
Looking for a vertical retention tip and adapter system that stays sharper, changes easier and holds tighter? Choose the K Series system's twist-on design and vertical retainer, which together provide reliable retention and easy installation and removal.
| Name | Description |
|---|---|
| IMPROVE YOUR PRODUCTIVITY | Low-profile shape provides optimal sharpness, penetration and digging ability throughout the tip life. |
| EXTEND LIFE | More wear material can effectively be used before the tips are changed, adding 10-15% more usable life. |
| INCREASE DURABILITY | The tip and adapter fit together precisely to reduce tip movement and adapter wear. |
| STAY SAFE & REDUCE MAINTENANCE COSTS | One-piece vertical retainer allows for easy installation and removal. |
| SIMPLIFY INSTALLATION | Rails on both sides of the adapter and a twist-on design hold the tip in place, allowing for quicker installation. |

K SERIES TIP OPTIONS
Below are the tip shapes best suited for the wide range of jobsite conditions performed by hydraulic excavators. We also offer additional K Series tips more commonly used with wheel loaders. Your Cat dealer can help you choose the one that offers the right balance of penetration and wear life for your application.

 | GENERAL PURPOSE » General Purpose tips are symmetrical and the baseline for other tip styles. All wear comparisons are to the General Purpose tip unless otherwise noted. | |
 | WIDE » Wide tips are used to maintain smooth trench floors and in low-abrasion, easy-to-penetrate material. | |
 | PENETRATION PLUS » Penetration Plus tips feature 25% more wear material and a leading edge with 25% less cross-sectional area. They self-sharpen as they wear. | |
 | PENETRATION » Penetration tips are ideal for densely compacted materials. They feature a leading edge with 60% less cross-sectional area— allowing for maximum penetration—and a single center rib that self-sharpens as it wears. These tips are available with A.R.M.* | A.R.M. |

BASE EDGE SYSTEMS
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.
| Name | Description |
|---|---|
| INCREASE DURABILITY | 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. |
| SAVE INSTALLATION & REPLACEMENT TIME | 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. |
| OPTIMIZE MACHINE PERFORMANCE | Base edges are designed by Caterpillar engineers for optimal performance on specific machines. |
GET MORE ACCURACY
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.
| Image | Description |
|---|---|
 | BOLT-ON CUTTING EDGE |
 | STRAIGHT |
 | SPADE |
Lasers place the adapters within 0.1 mm of specifications.
BUTTERBEAD BASE EDGE ASSEMBLY
DURABLE PROTECTION COMBINED WITH SHORTER INSTALLATION TIMES.
The protection you need, with no preheating required—that's what you get with butterbead weld prep. This technique, which involves applying a layer of weld to a heat-treated, higher hardness part, makes it possible to weld a base edge to a bucket without preheating the hardened part. Choose from two shapes (straight and spade) on cutting edges thicker than 50mm and three levels of build to get the right protection for your application.
| Name | Description |
|---|---|
| SPEED UP YOUR INSTALLATION TIME | Weld prep eliminates the need for preheating, shortening edge installation time by 30-50%. |
| GET MORE DURABILITY | Base edges have the proper butterbead weld because it is applied in the factory. |
BASE EDGE END PROTECTION (BEEP)
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.
| Name | Description |
|---|---|
| BOOST YOUR UPTIME | Through-hardened Rc ~45 (Br ~3.0) weldable steel is easily installed in the shop or the field. |
| EXTEND LIFE | Extended base edge end protects adapter corner welds. |
| SPEED UP INSTALLATION | Height and bevel are matched to the base edge, so there's no additional fabrication. |
SIDE & EDGE PROTECTION

BOLT-ON HALF ARROWS, TOP COVERS, CUTTING EDGES & WELD-ON SHROUDS
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.
| Name | Description |
|---|---|
| SIMPLIFY MAINTENANCE | Individual pieces that protect the edge can be changed independently. |
| ENHANCE DURABILITY | Half arrows cover the leading edge for smooth material transition. |

BUCKET SELECTION GUIDE
We offer four standard bucket durability categories suitable for any application. Each category is based on the bucket's intended durability when used in the recommended application and material.
| Image | Description |
|---|---|
 | GENERAL DUTY |
 | SEVERE DUTY » For a wide range of impact and abrasion conditions including mixed dirt, clay and rock. Example: Digging conditions where Penetration Plus tip life ranges from 400 to 800 hours. » HD buckets are a good “center line” choice, or starting point, when application conditions are not well known. |
 | EXTREME DUTY » For a wide range of impact and abrasion conditions including mixed dirt, clay and rock. Example: Digging conditions where Penetration Plus tip life ranges from 400 to 800 hours. » HD buckets are a good “center line” choice, or starting point, when application conditions are not well known. |
 | EXTREME DUTY |
CHOOSING THE RIGHT DURABILITY.
Choosing the wrong bucket can easily reduce production and increase operating costs by 10-20% or more. It can also cause unnecessary wear and fatigue for both machine and bucket. Contact your local Cat dealer for more detailed information on choosing the right excavator, bucket and work tool attachment combinations to meet your application needs.
