The Simpson SDS-plus Solid-Tip Carbide Drill Bit (1/4 in. x 6-1/4 in.) is a premium-quality, professional-grade rotary hammer bit engineered for demanding drilling applications in concrete and masonry. Built to precise tolerance requirements and conforming to ANSI Standard B212.15, this hardened steel bit combines a solid-tip carbide head, a high-performance alloy body, and an optimized flute design to deliver fast, consistent hole drilling with extended service life across a wide range of job site conditions.

Key Features

• Uniformly brazed carbide inserts - provide consistent contact and secure bonding across the entire tip, resulting in longer bit life and fewer replacements over time
• Chromium-nickel-molybdenum steel alloy body - delivers superior hammering quality and extended service life, making this bit well-suited for heavy, repetitive use in concrete and masonry
• Heat-treatment procedures and shot-peened finish - increase surface hardness, improve drilling speed, reduce drill bit wear, and strengthen the bit's resistance to bending forces for more reliable performance under load
• Chisel-shaped drill-bit head - penetrates material efficiently and directs concrete dust into the multi-flute spiral, keeping the hole clean and reducing heat buildup at the tip
• High-volume, multi-flute spiral - quickly channels concrete dust out of the hole during drilling, improving drilling speed and reducing the effort needed to complete each bore
• Solid-tip carbide drill bit construction - provides a robust, impact-resistant cutting surface purpose-built for rotary hammer use in hard base materials
• SDS-plus shank - enables tool-free bit changes and maintains a secure, positive connection to the rotary hammer for efficient power transfer with every stroke
• Conforms to ANSI Standard B212.15 - ensures the bit meets established dimensional and performance tolerances, giving professionals confidence in fit, compatibility, and quality

Why This Product

• Professional-grade durability engineered for the long haul - the combination of uniformly brazed carbide inserts, a chromium-nickel-molybdenum alloy body, and a heat-treated, shot-peened finish means this bit holds up under demanding rotary hammer use far longer than standard bits, reducing downtime and replacement costs
• Faster drilling with less effort - the chisel-shaped tip and high-volume multi-flute spiral work together to break material efficiently and clear concrete dust continuously, so holes are completed faster and with less resistance throughout the full 4 in. drilling depth
• Built to a recognized industry standard - ANSI Standard B212.15 compliance confirms this bit meets verified dimensional tolerances, so it fits correctly and performs predictably in compatible SDS-plus rotary hammers without guesswork
• Precision manufacturing for consistent results - produced to the highest industry standards, this bit incorporates proprietary features that enhance both durability and drilling speed while maintaining the dimensional accuracy required for anchor and fastener installation in concrete and masonry

Frequently Asked Questions

What type of shank does the MDPL02506S use, and which rotary hammers is it compatible with?

The MDPL02506S features an SDS-plus shank, which is the standard shank type used in a wide range of rotary hammer drills. This shank design allows for tool-free bit changes and provides a secure, positive connection for efficient power transfer during drilling.

What is the maximum drilling depth this bit can achieve?

This bit provides a drilling depth of 4 in. It has an overall length of 6-1/4 in. and a diameter of 1/4 in., making it suitable for applications requiring moderate-depth holes in concrete and masonry.

How does the bit's construction help extend its service life?

The bit features uniformly brazed carbide inserts for longer bit life, a chromium-nickel-molybdenum steel alloy body for hammering quality and extended service life, and heat-treatment procedures combined with a shot-peened finish that increase surface hardness, reduce drill bit wear, and improve resistance to bending forces.

Does this drill bit meet any recognized industry standards?

Yes. The MDPL02506S conforms to ANSI Standard B212.15, ensuring it meets established dimensional and performance tolerances required for professional-grade SDS-plus carbide drill bits.
