# Bosch T3911SC 1-3/16 in. Carbide SDS-Plus Core Bit

Bosch T3911SC SPEEDCORE is a thin-wall carbide core bit for making holes in masonry, brick, and block. Its SDS-Plus shank is intended for compatible rotary hammers and hammer drills, but the listing specifies rotary mode only. The integrated pilot-bit-and-mandrel design is convenient, while the stated package contains the core bit alone.

## Customer feedback

Customer feedback reports clean-looking holes, cutting performance, speed, and durability, including a mention of use in cured concrete. Some feedback also describes the carbide tips as retaining useful life and considers the bit good value. Ease of removing the bit after use is disputed. These are customer impressions rather than performance guarantees. The listed ejector hole is relevant to core removal, but the feedback does not establish that it eliminates removal difficulties.
