Easily Protect Your Road Milling Machines From Excessive Wear

New road milling drums are expensive to purchase and maintain. Most companies focus on bit life, and ignore a simple step to prevent excessive wear on the bit holders and stand offs.

Protecting the tool bit holders or pockets, is the first step in proper maintenance and up keep of your milling drums.


Many road milling drums like the photo above have stand offs positioning the bits at the proper diameter. The holders and standoffs see tremendous wear from continual impact and abrasion from the chips scraped off of the pavement. The drum pictured is protected from most of the wear by the JADCO HARDGUARD blocks welded in place.

Damaged stand offs and bit holders are very labor intensive to replace. Downtime is expensive and could impact completing a project on time.

Using JADCO’s HARDGUARD Chocky Blocks can extend the life of the bit holder significantly. It is an inexpensive and effective way to maintain your equipment, to assure the longest possible uptime.

HARDGUARD protects the bit holders and standoffs, the most time consuming and expensive items to replace on road milling machines.

Not all drums have stand offs. Bit holders are made of medium carbon steel. When worn, they often lose the bit and bit holder, causing even more damage to your equipment. Protecting the front of the bit holder dramatically extends the life of your equipment.
