The Simpson SDS-Plus Solid-Tip Carbide Drill Bit (3/8 in. x 6-1/4 in., 4 in. Drilling Depth) is a professional-grade rotary hammer bit engineered to handle demanding concrete, masonry, and hard substrate drilling applications with consistent precision. Produced to the highest industry standards, this bit incorporates a solid-tip carbide head, a chromium-nickel-molybdenum steel alloy body, and a high-volume multi-flute spiral design that work together to maximize drilling speed, reduce wear, and keep holes clean during use.

Key Features

• Uniformly brazed carbide inserts - deliver consistent contact and bonding strength across the full tip, resulting in longer bit life and reliable performance across repeated drilling cycles
• Chromium-nickel-molybdenum steel alloy body - provides the structural integrity needed to withstand rotary hammer impact forces, ensuring hammering quality and extended service life on tough materials
• Heat-treatment procedures and shot-peened finish - increase surface hardness and resistance to bending forces, reduce drill bit wear, and improve drilling speed so the bit holds up under heavy professional use
• Chisel-shaped drill-bit head - penetrates material efficiently and actively directs concrete dust into the multi-flute spiral, keeping the cutting edge clear for faster, cleaner holes
• High-volume, multi-flute spiral - quickly channels concrete dust out of the hole during drilling, improving drilling speed and reducing the buildup that can slow progress or damage the bit
• Solid-tip carbide construction - provides reliable penetration in hard substrates such as concrete and masonry, making this bit well suited for anchor installation and structural drilling tasks
• SDS-plus shank - enables quick, tool-free bit changes on compatible SDS-plus rotary hammer drills, saving time on the job and ensuring a secure, wobble-free fit during operation
• Conforms to ANSI Standard B212.15 - meets established dimensional and performance tolerances, giving professionals confidence that the bit will perform predictably and fit within spec-driven applications

Why This Product

• Built for professional-grade durability - the combination of uniformly brazed carbide inserts, a chromium-nickel-molybdenum alloy body, and a heat-treated, shot-peened finish means this bit is engineered to outlast standard carbide bits in high-frequency concrete and masonry drilling
• Smarter dust management for faster drilling - the chisel-shaped head and high-volume multi-flute spiral work as a system to continuously evacuate concrete dust from the hole, maintaining drilling speed and reducing rework caused by clogged or overheated bits
• Precision you can count on - compliance with ANSI Standard B212.15 means dimensional tolerances are tightly controlled, making this bit a dependable choice for anchor installations and applications where hole diameter accuracy directly affects load performance
• Seamless compatibility with SDS-plus tools - the SDS-plus shank delivers a fast, secure connection to any compatible rotary hammer, eliminating chuck adjustments and keeping your workflow moving on multi-hole concrete drilling jobs

Frequently Asked Questions

What type of shank does the MDPL03706S use?

This drill bit features an SDS-plus shank, which allows for quick, tool-free bit changes and is compatible with SDS-plus rotary hammer drills.

What is the maximum drilling depth for this bit?

The MDPL03706S has a drilling depth of 4 in., with an overall length of 6-1/4 in. and a diameter of 3/8 in.

What makes the carbide tip on this bit durable?

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

How does this bit handle concrete dust during drilling?

The chisel-shaped drill-bit head penetrates the material and directs concrete dust into the high-volume, multi-flute spiral, which quickly channels the dust out of the hole to improve drilling speed and keep the work area cleaner.
