BOSCH HC89 Core Bit Centering Drill Bit – 2″ Carbide SDS-Max

Description

Product Overview

The BOSCH HC89 core bit is a purpose‑built centering drill designed for the toughest masonry applications. Constructed from high‑grade carbide, the cutting tip maintains sharpness even after repeated use on reinforced concrete, brick, and stone. The SDS‑Max shank provides a secure, torque‑rich connection to compatible hammer drills, ensuring that power is transmitted directly to the cutting edge without loss. With a 2‑inch (50 mm) cutting diameter, this bit creates clean, round holes that are ready for rebar, conduit, or anchor installation. The bit features a 120‑degree cutting angle and a dual‑flute spiral flute design that efficiently evacuates debris, reducing heat buildup and extending tool life. Its classic yellow‑1052 color coding makes it easy to identify in a busy tool chest, while the solid rectangular shape offers stability during high‑impact drilling. The HC89 is a single‑piece unit, weighing only 0.01 oz, which means it adds minimal weight to your drill, allowing for longer periods of use without fatigue. The product is backed by Bosch’s reputation for engineering excellence and is listed among the top core drill bits in the Tools & Home Improvement category, reflecting its popularity among contractors and trade professionals.

Usage

This core bit excels in a variety of real‑world scenarios. On construction sites, it is the go‑to solution for creating precise openings in concrete slabs for electrical conduit, plumbing pipes, and structural reinforcement. The carbide tip’s durability makes it suitable for drilling through dense, reinforced concrete without the need for frequent bit changes. In renovation projects, the HC89’s accurate centering capability helps preserve surrounding finishes, reducing the risk of cracks or chipping when cutting through existing masonry walls. The SDS‑Max shank ensures compatibility with most heavy‑duty hammer drills, allowing users to take advantage of high impact energy for faster penetration. Because the bit is designed to handle both dry and wet conditions, it can be used in environments where water is present, such as underground utility installations. The lightweight design reduces operator fatigue, making it ideal for extended use in large‑scale projects where dozens of holes may be required. Whether you are a seasoned contractor, a skilled tradesperson, or a serious DIY enthusiast tackling a major remodel, the HC89 delivers consistent performance across all typical masonry drilling tasks.
