The Simpson 1/4 in. x 14 in. SDS-Plus Carbide 2-Cutter Head Drill Bit is a premium-quality, professional-grade carbide-tipped rotary hammer bit engineered to the highest industry standards for demanding concrete and masonry drilling applications. Built on a chromium-nickel-molybdenum steel alloy body with uniformly brazed carbide inserts and finished through a rigorous heat-treatment and shot-peening process, this bit is designed to meet precise tolerance requirements while delivering exceptional durability, drilling speed, and ease of use on the job site.

Key Features

• Uniformly brazed carbide inserts - bonded consistently across the cutting head for longer bit life and reliable performance hole after hole
• Centering tip design - facilitates easy spot drilling so you can position the bit accurately before committing to the full bore
• Chromium-nickel-molybdenum steel alloy body - ensures hammering quality and extended service life under the repeated impact loads of rotary hammer drilling
• Heat-treatment procedures and shot-peened finish - increase surface hardness, improve resistance to bending forces, reduce drill bit wear, and contribute to faster drilling speeds
• ANSI Standard B212.15 compliance - confirms the bit meets established industry dimensional and performance standards, giving professionals confidence in fit and function
• Chisel-shaped 2-cutter drill-bit head - penetrates concrete and masonry efficiently while directing concrete dust into the multi-flute spiral to keep the cutting zone clear
• High-volume, multi-flute spiral - quickly channels concrete dust from the hole, improving drilling speed and reducing the need to retract the bit during operation
• SDS-plus shank - enables quick, tool-free bit changes and is compatible with standard SDS-plus rotary hammer drills for streamlined workflow on site

Why This Product

• Built to outperform through superior materials - the combination of carbide inserts, a chromium-nickel-molybdenum alloy body, and a heat-treated, shot-peened finish means this bit resists wear, handles bending forces, and stays sharp longer than standard masonry bits
• Extra overall length where it counts - at 14 in. overall with a 12 in. drilling depth, this bit clears the depth requirements common in anchor installation and through-fastening applications without the need for extensions
• Engineered for speed, not just strength - the chisel-shaped head and high-volume, multi-flute spiral work together to move concrete dust out of the hole continuously, keeping drilling fast and reducing operator fatigue on repetitive bores
• Professional-grade standards from a trusted brand - manufactured to ANSI Standard B212.15 and built to precise tolerance requirements, this Simpson bit is part of a complete line of premium drilling and demolition tools designed for professional contractors

Frequently Asked Questions

What type of shank does the MDPL02514 drill bit use?

The MDPL02514 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 drilling depth and overall length of this bit?

This drill bit has a drilling depth of 12 in. and an overall length of 14 in., with a 1/4 in. diameter - giving it the extra length needed to clear depth requirements in anchor and fastening applications.

What makes this drill bit more durable than standard bits?

The MDPL02514 features uniformly brazed carbide inserts, a chromium-nickel-molybdenum steel alloy body, and a heat-treatment process combined with a shot-peened finish. Together, these characteristics 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. This design improves drilling speed and helps keep the hole clear during operation.
