Bosch SDS-Plus 2ct 5/32X4X6 25-Pack

The Bosch HC2001B25 delivers 25 carbide-tipped rotary hammer bits measuring 5/32” diameter with 4” usable length and 6” overall length. These bits feature Bosch’s 15% faster drilling performance compared to their S4L model — a measurable improvement that translates to real time savings on high-volume concrete work. For contractors drilling hundreds of anchor holes per job, that 15% adds up.

Performance That Matters for Montana Contractors

The proprietary hardening process yields more holes per bit, which matters when you’re 60 miles from the nearest supply house. Bosch-made carbide tips handle heavy loads without chipping or dulling prematurely. The optimized brazing process ensures the tip stays attached even in tough applications — because nothing kills productivity like a carbide tip separating mid-hole.

The 4-flute design removes dust faster and keeps the bit cooler than traditional 2-flute designs. Cooler bits last longer. Simple physics that pays dividends over a 25-pack’s lifespan.

Precision Anchoring Technology

The centric tip ensures quick, accurate starts in concrete — no walking across the surface trying to find purchase. Each bit includes a wear-mark that alerts when the tip wears beyond ANSI specification for precision anchoring. This visual indicator takes the guesswork out of compliance. When structural connections depend on accurate hole diameter, that wear mark becomes critical quality control.

Compatible with all SDS-Plus rotary hammers, including Bosch, Milwaukee, DeWalt, and other major brands. Installation requires no tools — insert the SDS-Plus shank into the chuck and rotate until it clicks. To remove, pull back the locking sleeve and pull the bit out.

The Bulk Value Proposition

At 25 bits per pack, this format targets contractors with serious concrete drilling volume. Applications include anchoring in concrete, through-hole drilling for rebar, dowels, and conduits, general masonry drilling, and high-volume bit usage.

The 5/32” diameter hits the sweet spot for common anchoring applications — large enough for strength, small enough to minimize concrete damage. Bosch advertises this as 15% faster than their S4L series, and it competes directly with Milwaukee’s 48-20-7501 bulk pack in the same size range.

For Montana contractors handling commercial projects, infrastructure work, or any job requiring dozens of anchor holes, the bulk format eliminates constant resupply runs. Keep a pack in the gang box and focus on the work, not inventory management.

FAQ

What rotary hammers work with these bits? All SDS-Plus rotary hammers, including Bosch, Milwaukee, DeWalt, and other major brands with SDS-Plus chucks.

How do I know when to replace the bit? Each bit includes a wear-mark that alerts when the tip wears beyond ANSI specification for precision anchoring. When you see the mark, swap the bit.

What’s the actual cutting length? The flute length and usable length are both 4 inches, with 6 inches total length.

What’s included in the box? 25 Bosch 5/32 in. x 4 in. x 6 in. SDS-Plus Bulldog Rotary Hammer Bits.

Is there a warranty? Manufacturer’s warranty typically covers product defects only. Retailers like Walmart and FastenMSC offer 30-day return policies for unopened items.
