Minerallac 59986 Sds Rotary Hammer Drill Bit

Product Description

The MINERALLAC 59986 is a 1/4-inch by 6-inch SDS rotary hammer drill bit designed for use in SDS-style rotary hammer tools. The SDS shank provides a secure, tool-free bit change and positive engagement with the hammer mechanism, delivering efficient drilling through concrete, masonry, and similar hard substrates. At 0.11 pounds, it is a lightweight accessory suited for overhead and confined-space work. Electricians, plumbers, and HVAC technicians commonly use bits of this type when penetrating concrete block, poured concrete, or CMU walls during rough-in work.

This bit is sized at 1/4 inch in diameter with a 6-inch overall length, making it well suited for drilling anchor holes, conduit penetrations, and sleeve openings in residential and light commercial construction. The SDS drive interface is compatible with standard SDS-plus rotary hammer chucks. It is a Relton-manufactured bit distributed under the MINERALLAC line, designed for repetitive production drilling in masonry applications.

Installation Notes

Installation of this bit requires an SDS-plus rotary hammer; it is not compatible with standard keyed or keyless drill chucks. Electricians, plumbers, and HVAC technicians should confirm the target substrate before drilling and use appropriate eye and respiratory protection when working with concrete or masonry dust. Follow applicable OSHA silica dust exposure requirements when drilling masonry in enclosed spaces. Inspect the bit for wear or carbide tip damage before each use and replace if the tip is cracked or the flute is damaged.
