The Simpson SDS-Plus Solid-Tip Carbide Drill Bit, 1/2 in. x 12-1/4 in. with 10 in. Drilling Depth is a premium-quality, professional-grade 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 and tipped with solid carbide, this bit pairs an SDS-plus shank with proprietary design features that work together to maximize drilling speed, extend service life, and maintain precise tolerances hole after hole - making it a dependable choice for contractors and tradespeople who drive anchors and fasteners into concrete regularly.

Key Features

• Uniformly brazed carbide inserts - consistent bonding across the tip means the carbide stays locked in place under repeated impact, resulting in longer bit life and fewer mid-job replacements
• Chromium-nickel-molybdenum steel alloy body - this high-grade steel composition absorbs the shock loads generated by rotary hammer drilling, ensuring reliable hammering quality and extended service life even in heavy daily use
• Heat-treatment procedures and shot-peened finish - the combination increases surface hardness, boosts drilling speed, reduces bit wear, and improves resistance to bending forces, keeping the bit straighter and sharper over time
• Chisel-shaped drill-bit head - the geometry penetrates concrete and masonry efficiently while actively directing concrete dust into the multi-flute spiral, reducing resistance and heat buildup at the tip
• High-volume, multi-flute spiral - rapidly channels concrete dust out of the hole as you drill, maintaining a clear cutting path that improves drilling speed and reduces the effort required to reach full depth
• Conforms to ANSI Standard B212.15 - verified dimensional compliance means the bit fits SDS-plus chucks correctly and delivers the hole tolerances required for anchor and fastener installations
• SDS-plus shank - the industry-standard connection locks securely into SDS-plus rotary hammers from a wide range of tool manufacturers, allowing quick, tool-free bit changes on the job

Why This Product

• Professional-grade construction from start to finish - Simpson specifies uniformly brazed carbide inserts, a chromium-nickel-molybdenum steel alloy body, heat treatment, and a shot-peened finish together in a single bit, so buyers get a complete package of durability enhancements rather than a single isolated upgrade
• Optimized dust extraction keeps pace with demanding drilling schedules - the chisel-shaped tip and high-volume, multi-flute spiral work as a system to move concrete debris out of the hole continuously, which translates to faster cycle times and cooler operating temperatures for the bit
• 10 in. drilling depth on a 12-1/4 in. overall length - the extra reach supports deep anchor and through-hole applications in concrete walls and slabs where shorter bits cannot achieve the required embedment depth
• Manufactured to verified tolerances under ANSI Standard B212.15 - compliance with this standard gives installers confidence that every hole meets the dimensional requirements called out in anchor manufacturer specifications, reducing the risk of failed pull tests or rework

Frequently Asked Questions

What type of shank does the MDPL05012S use, and which tools is it compatible with?

The MDPL05012S features an SDS-plus shank, which is a standard connection type compatible with SDS-plus rotary hammer drills from a wide range of manufacturers.

What is the drilling depth and overall length of this drill bit?

This drill bit has an overall length of 12-1/4 in. and provides a maximum drilling depth of 10 in., giving it extra reach for deep anchor and fastener applications in concrete and masonry.

How does the solid-tip carbide design benefit drilling performance?

The solid-tip carbide head is chisel-shaped to penetrate material efficiently while directing concrete dust into the high-volume, multi-flute spiral. This design quickly channels debris out of the hole, improving drilling speed and reducing wear on the bit.

What quality standards does this drill bit meet?

The MDPL05012S conforms to ANSI Standard B212.15 and is manufactured to the highest industry standards. Its chromium-nickel-molybdenum steel alloy body undergoes heat-treatment procedures and a shot-peened finish to increase surface hardness, reduce wear, and improve resistance to bending forces.
