PHD-100T Screw Point Auger Tip – Threaded Replacement

Description

The AG-GO PHD-100T screw point auger tip is a threaded replacement point for compatible post hole diggers and auger heads. Its spiral-shaped working profile engages the ground ahead of the cutting blades and flighting, helping the auger establish its starting location and begin tracking into the soil. Hardened steel construction supports repeated agricultural, fencing, landscaping, and construction work.

Unlike a fish-tail point, the PHD-100T presents a screw-style profile to the ground. Rotation allows that profile to engage the soil and help draw the auger downward when the ground conditions and complete digging system are suitable. The mounting connection must match the existing receiver, so this replacement should not be selected by appearance, machine type, or auger diameter alone.

Screw Point Auger Tip for Ground Engagement and Tracking

The pilot point is the first auger component to contact the digging surface. When it becomes rounded, chipped, or badly worn, the auger may have more difficulty establishing the intended hole location. Replacing the point can help restore the ground-engaging shape designed into the auger head.

The PHD-100T may be considered for compatible jobs such as:

• Drilling holes for farm, pasture, and property-line fencing
• Setting gate posts, signs, poles, and agricultural structures
• Preparing planting holes for trees and large shrubs
• Servicing agricultural or commercial drilling equipment

Clay, compacted soil, gravel, roots, and abrasive material can affect performance and tip life differently. A screw point should not be forced through large rocks, buried construction debris, or immovable objects the post hole digger was not designed to cut. Excessive downward pressure can transfer damaging loads into the tip, auger head, flighting, shaft, gearbox, driveline, or hydraulic motor.

This threaded replacement may serve compatible three-point post hole diggers, tractor-mounted augers, skid steer auger drives, and other properly matched equipment. Those machine categories do not establish direct fit. The auger receiver, mounting threads, seating surface, surrounding clearance, and complete system must match the PHD-100T.

Threaded Installation, Compatibility Checks, and Safe Use

Before ordering, compare the original point’s thread diameter, pitch, direction, usable threaded length, seating surface, and installed clearance. Measure clean, unworn surfaces whenever possible. Dirt, corrosion, burrs, and damaged threads can affect both measurement and installation.

Before service, shut down the machine, disengage the PTO or hydraulic drive, relieve stored energy, and support the auger against unexpected movement. Clean the receiver and inspect it for cracks, distortion, stripped threads, or excessive wear. Start the PHD-100T by hand when possible to confirm smooth engagement, then tighten it according to the applicable equipment instructions. Do not force crossed threads or assume one torque or thread-locking method applies to every auger.

The PRO-Link post hole digger parts guide compares threaded screw points with fish-tail tips, cutting blades, and complete auger heads. Buyers wanting a threaded fish-tail profile can compare the PHD-100FT threaded auger tip. Equipment using bolt-on tip retention requires a product such as the PHD-100F fish tail auger tip instead.

Before drilling, contact 811 to request underground utility markings. Operators should also review Ohio State University’s post hole digger safety guidance, keep guards and shields installed, keep bystanders away, and stop all movement before inspection or adjustment.

Inspect the screw point, mounting threads, receiver, cutting blades, flighting, shaft, driveline, gearbox or hydraulic motor, and guards before use. Replace loose, cracked, bent, chipped, or badly worn parts. The PHD-100T is covered by PRO-Link’s one-year limited warranty against manufacturer’s defects, subject to the complete terms.

Questions & Answers

How does a screw point auger tip differ from a fish-tail tip?

A screw point uses a spiral-style ground-engaging profile. A fish-tail tip uses projecting edges with a different shape. Choose the design and mounting method specified for the compatible auger.

Will the PHD-100T fit every threaded post hole digger?

No. Confirm the thread diameter, pitch, direction, usable length, seating surface, receiver condition, and operating clearance before ordering or installation.

When should the PHD-100T screw point be replaced?

Replace it when the working profile becomes badly rounded, chipped, cracked, loose, unevenly worn, or damaged at the mounting threads. Inspect the receiver and cutting components at the same time.
