The PT‑2000‑109 Counterbore Sleeve Cutting Bit is a premium-grade carbide cutter bit engineered for heavy-duty diesel engine block repair applications. Specifically designed for use with the PT-2050-D M52050 counterbore/sleeving system, this bit enables precise machining of engine block counterbores to prepare for press-fit repair sleeves or bushings.
When engine blocks show wear or damage in the counterbore seating ledge area, a reliable cutter bit is essential for restoring proper depth, alignment, and finish before inserting a repair sleeve. The PT-2000-109 delivers clean, accurate machining, providing a flat, concentric surface that meets OEM and rebuild standards.

-
Manufactured with durable carbide for long wear life and consistent cut quality.
-
Designed to produce precise flat and concentric surfaces in the counterbore region, critical for ensuring reliable liner and sleeve support.
-
Streamlines block repair by simplifying the machining step ahead of sleeve installation, reducing block scrap risk and rework.
-
Ideal for engine rebuild shops, heavy-duty service centers, and diesel engine remanufacturers tackling high-hour blocks.
Typical Applications
Use the PT-2000-109 when preparing engine blocks for installation of lower repair sleeves or bushings—particularly after material removal, over-boring, or damage in the counterbore support surface. Compatible with various heavy-duty diesel engines requiring top deck or lower deck repair where PT-2050-D equipment is in use. Refer to machine shop procedures for correct setup, speed, feed, and depth of cut.
