Bucket Tooth 5KC3SB 5KC Keech

Compatible with the following equipment:

5KC3SB Blade Teeth

The 5KC Keech or MT03 Hitachi style is Australia's most common tooth system for mini excavators and skid steers up to 3 tonnes. These teeth are secured with either a nested two-roll-pin system or a single heavy-duty coiled spring pin, installed vertically. If your machine in this class uses a roll-pin retention method, this is likely your tooth type. The primary exceptions are ECH excavator buckets and Hughes 4-in-1 buckets made after 2007, which use a specific "03 Roll Pin" style tooth, also widely available.

Blade or Twin Tiger Teeth?

Blade Teeth are the ideal all-rounder, offering a long service life due to their large wear area. Twin Tiger Teeth feature sharper points for easier penetration in hard or compacted ground, but their narrower design leads to faster wear. A simple guideline is to use Blade teeth for general work and switch to Twin Tigers when your machine struggles to dig into tougher material.

Built for Performance and Longevity

Lucas Parts teeth are manufactured to the highest quality standards to ensure this performance. Every tooth and adapter is forged from high-quality alloy steel, achieving an impact strength greater than or equal to 20J for superior toughness. They are then hardened to a range of 47-52 HRC (Rockwell Hardness), creating an extremely durable wear surface that maximizes service life under demanding conditions.
