Product Description

OZ-Post® Jackhammer Driving Kit — JDK-10 — Fastest Way to Install OZ-Post® Anchors

• Production-Speed Installs — Jackhammer-driven system sets anchors quickly on long runs and tough soils
• Kit Includes Essentials — OH-01 jackhammer driver bit + HSP-T4 red hammer-spacer for 4×4 (T4) sleeves
• Fits Standard Jackhammers — OH-01 bit fits a 1-1/8″ hex jackhammer chuck (common rental size)

• Durable, Reusable Tools — Built to handle daily jobsite use

The JDK-10 Jackhammer Driving Kit (OZ-Tools Item 20480) is the go-to driver setup when you want the fastest OZ-Post® installation. The included OH-01 bit drops into a standard 1-1/8″ hex jackhammer, while the HSP-T4 spacer centers the bit inside T4 (4×4) sleeves so impacts land square and controlled. Add the spacer that matches your other anchor families (e.g., I-Series, T6, T46) to extend the kit across your projects.

Why Choose This

• Speed at scale — Ideal for fence lines, sign runs, and crews on a schedule
• Cleaner installs — Centered driver helps maintain plumb and protects sleeves from edge strikes
• Flexible system — Use anchor-specific spacers to cover multiple post sizes

Specifications

Installation

Lay out posts and call 811 to locate utilities. Insert the anchor-family spacer into the sleeve, seat the OH-01 bit on top, and drive with a jackhammer—checking plumb as you go with a post level. Leave ~1″ of sleeve above grade for wood posts (helps shed water and protect from trimmers). For round steel anchors, use the OH-02 driver and the round family’s spacer where specified.

Buying Guide

• Manual vs. jackhammer: Short runs or tight access? Consider the MDK-13 Manual Driving Kit. Long runs or dense soils? JDK-10 is faster and easier on crews.
• Spacers for other anchors: Add the spacer that matches your sleeve size—e.g., HSP-I25 (2-1/2″ I-Series).
• Round steel anchors: Use the OH-02 Jackhammer Driver Bit with GB/HB/IS-series anchors.

Frequently Asked Questions

What’s included in the JDK-10?

The OH-01 jackhammer driver bit and the HSP-T4 red hammer-spacer for T4 (4×4) sleeves.

Will it fit my jackhammer?

Yes, the OH-01 uses a 1-1/8″ hex shank—common on rental jackhammers.

Can I use it with other OZ-Post anchors?

Yes. Add the spacer for that anchor family (I-Series, T6, T46). Round steel anchors use the OH-02 driver bit.

When would I use the manual kit instead?

On short runs, in tight spaces, or where power tools aren’t practical, the MDK-13 slide-hammer kit is a good choice.
