Strongarm Diamond Tip GSA Core Drill Bit (DC3) 3/8 x 6, Aero Space Lubricant Provided with Each Drill

Diamond Tip GSA Core Drill Bits: The cost effective and easy way to drill GSA carbide matrix hard plate, relsom, maxalloy, etc. Additional aero space lubricant provided with each drill.

The Strongarm Diamond Tip GSA Core Drill Bit (DC3) ($3/8" \times 6"$) is a heavy-duty, professional-grade tool specifically engineered for safe technicians, locksmiths, and security professionals. It is the industry standard for penetrating carbide matrix hardplates used in high-security GSA-rated containers and commercial safes.

Product Overview

The DC3 diamond core bit is designed to overcome materials that traditional carbide bits cannot handle, such as Relsom, Maxalloy, and composite hardplates. Instead of grinding away at the entire surface, this bit "cores" through the material, creating a clean circular path. This method is significantly faster, generates less heat, and reduces the risk of bit failure or "chatter" during the drilling process.

Key Features

  • Industrial Diamond Coating: Features a high-density, electroplated diamond tip specifically optimized for cutting through chunks of carbide embedded in a matrix.

  • Efficient Coring Action: The hollow core design minimizes the surface area of the cut, allowing for faster penetration and cooler operating temperatures.

  • Aero Space Lubricant Included: Each drill bit comes with a sample of specialized Aerospace Lubricant to flush out abrasive debris and maintain the integrity of the diamond tip.

  • Professional Grade Durability: Built to withstand the high-torque requirements of rotary drilling in specialized security hardware.

  • Precision Sizing: The $3/8"$ diameter provides a wider path, ideal for access points that require more clearance than standard $1/4"$ or $5/16"$ bits.

StrongArm Drill Bits SADDC3 – Frequently Asked Questions

1) What will a Strongarm DC3 diamond core bit actually drill through on a GSA safe?
The DC3 is built for the hardplate materials that stop ordinary carbide: carbide matrix, Relsom, Maxalloy, and GSA-rated hardplates found in high-security containers and commercial safes. Rather than grinding the full face of the hole, it cores a circular path through the plate, which cuts faster and runs cooler than trying to chew the whole diameter.
2) Can I run the DC3 core bit in hammer drill mode?
No. The DC3 is rotary mode only. Running it on a hammer or impact setting will wreck the electroplated diamond tip. Set the drill to straight rotation, keep steady pressure, and let the coring action do the work.
3) What size hole does the Strongarm DC3 bit cut, and how deep can it reach?
The DC3 cuts a 3/8 inch diameter and the bit is 6 inches long overall. The 3/8 path gives more clearance at the access point than the 1/4 inch or 5/16 inch bits in the same family, which matters when you need room to work a scope or a tool through the hole afterward.
4) Why use a diamond core bit instead of a carbide tip bit on hardplate?
Carbide bits fail on carbide matrix plate because they are trying to cut material as hard as they are, across the whole hole face. The DC3 uses an electroplated industrial diamond tip and a hollow core, so it removes only a thin ring of material. Less surface area in the cut means faster penetration, lower heat, and less chatter, which is the usual cause of a bit walking or snapping. On softer plate a standard carbide bit is still the cheaper route; the diamond core is for the plates that stop carbide.
5) Do I need to buy cutting lubricant separately for a diamond core bit?
Not with the DC3. An aerospace grade lubricant sample ships with each drill bit. Its job is to flush abrasive debris out of the cut so the diamond tip is not grinding through its own swarf, which is what kills these bits early.
6) What is the part number to order the 3/8 x 6 Strongarm diamond core bit?
It is the DC3, manufacturer part number 51100. Strongarm designates it by the DC3 model code, and the size that code covers is 3/8 x 6 inches.
7) Does the 3/8 inch DC3 come in other diameters or is that the only size?
The DC3 is a single configuration: 3/8 inch diameter, 6 inches long. Strongarm's diamond core line also runs in 1/4 inch and 5/16 inch, so if you want a smaller entry hole you are ordering a different bit, not a different option on the DC3.
